A/N: Hi everyone, I hope you enjoy my first attempt at this pairing, it will be based loosely on canon in a AU. Some minor facts have been changed for the benefit of the story like Tonks is one year younger. Another one is that in the books, its mentioned that Tonks never met Sirius till OotP, which to me never made sense. Sirius states that Tonks mum, Andromeda is his favorite cousin, so how could he have never met Tonks when she was a child if her Andy and Sirius were that close?

Summary: After the events of OotP and the return Voldemort, the Order decides to send it's best undercover Operative back to Hogwarts to watch over Harry. Posing as a sixth year student, Tonks becomes closer to Harry then her job asked of her. But when Bellatrix learns of Tonks's new role, she takes a personal interest in her niece and she's not the only Black who's gaze turns to Tonks. Tonks soon learns she cannot escape her heritage any longer and will be submerged into the world of Black no matter if she wants to or not. A thin line is all that separates love and hate, secrets will be revealed, views will change, loyalties will be tested.

Pairing: Harry/Tonks, Hermione/Ron (small mentions only), Bellatrix/OC

Timeline: This is a AU story set after the events of OotP and will progress through the events of HBP through the eyes and POV of Tonks mainly, but also Bellatrix and others chars here and there.

Disclaimer: The world of Harry Potter and the original storyline are not mine; they belong to J.K. Rowling.

Read and Review if you enjoy it and I'll try update it as often as I can :)


Chapter 1: Midnight Visit

As per usual it was yet another peaceful hot summer's night at Privet Drive, which gave no indication of the terror that had been rapidly spreading throughout the wizarding world. By the way the muggles of Privet Drive were still going about their daily lives; anyone would believe the United Kingdom was at the height of a golden era. One person living here knew better, a boy living at number 4. The boy who lived. Who unlike most of the other residents at Privet Drive, was far from asleep.

Harry lay restless on his plain single bed, drenched in sweat after waking to yet another nightmare. Although now wide awake, the images and sounds of his nightmare still haunted his mind. The face of his godfather, Sirius Black. The last look on his face before he died and vanished behind the veil. The triumphant cheer and mad cackles of his killer Bellatrix Lestrange.


A loud crack broke the peaceful silence, which was then followed by hurried footsteps that led to the door of number 4. The house laid dark and silent, its owners occupants most likely fast asleep.

The hand of a cloaked individual knocked hard against the door. A few seconds pause brought serenity back to the Drive, before once again being broken by a louder, harder, longer knock.

The lone figure waited as, through a glass panel in the door, a light flickered on. The occupants had awoken and one didn't sound too pleased about being woken in the middle of the night.

"Who the devil could that be at this time of night?" Came a very loud and very angry voice from somewhere beyond the door. The metallic jingle of locks being undone followed before the door opened wide to reveal a large angry red faced middle aged muggle, Harry's Uncle Vernon.

The light from the hallway illuminated the cloaked individual as they lowered their hood to reveal a young woman with bright bubble gum pink hair. Uncle Vernon's face drained of all colour and he trembled with anger as he realized just what kind of person had woken him up in the dead of night.

"Good evening." The young women said in a cheerful voice.

"Evening?... EVENING?!" Vernon bellowed, before then taking a deep breath. "It's almost midnight you blasted freak! Who the bloody hell are you and what the hell are you doing at my door?" He asked trying to overcome his rage and keep his voice low, as not to wake the neighbours whilst all the time adopting a very aggressive and intimidating posture.

"My name is Nymphadora Tonks, I'm a Auror and a member of the Order. I'm here to see Harry and deliver a message." Was the reply Tonks gave the muggle, as she pulled out a small letter as well as her wand from inside her robes. She had heard all about Harry's uncle and his... Attitude towards witches and wizards, a showing of a wand was a good way to bypass what could be a long list of unpleasantness. 'Slight intimidation. Fight fire with fire.' Tonks thought to herself.

"Who is it Vernon?" A proud stern female voice came from somewhere upstairs.

"It's nobody important." He called back over his shoulder. "Go back to bed my dear, I'll be back up shortly." A forced smile graced his mouth before turning back to look at Tonks.

"And you decided the best time to do this was in the dead of night? When we 'were' fast asleep?" Vernon growled through gritted teeth, relaxing his posture slightly at the sight of a wand, he knew his size and imposing body language wouldn't work here.

"Well..." Tonks cocked her head to the side slightly and smiled. "I did consider doing this during the day... But I thought you'd appreciate... Subtlety... That the cover of darkness provides less prying eyes... But if you prefer, I'll come back during the day tomorrow, then again the day after and then the day after that. And I'll keep returning, in full view of everyone, until I've seen Harry"

Tonks gave a short mocking bow then turned on her heels and started on the path away from the house, she had only taken a few steps before Vernon called her back. 'Beautifully done Tonks' She told herself with a small grin, then turned back to face the muggle.

"Come in and make it quick!" He grumbled in a defeated tone, best to let her do what she needs to do now rather than during the day where everyone can see him conversing with such a person.

"Thank you." With a smile and a nod Tonks headed inside, once inside she almost tripped over the helm of her cloak as she moved to the stairs. Her face warmed up as her cheeks turned a light shade of red from the embarrassment. Luckily Vernon was closing the door at the time and hadn't noticed.

"His room is-"

"I know which room is Harrys." Tonks replied quickly cutting him off. "And no need to wait up, I'll make my... Own, way out once I'm done here." With that, Tonks hurried up the stairs to Harry's room, leaving behind a livid Vernon who stormed off into the kitchen.

Tonks stood outside Harry's room, she dusted herself off and straightened her clothing before pulling out a small hand mirror and checked her hair. She sighed as she studied her reflection, her fingers softly tracing the faint outline of wrinkles around her eyes and the bags hidden under them. The weeks hadn't been kind to Tonks, with all the Death Eater activity and her grieving over Sirius; she barely had a decent nights rest. It was the main reason she had been chosen for this task, herself and Harry had felt the loss of Sirius more than others. She knew exactly how he felt and would be able to relate. 'Or at least I hope so'

It had been only a few weeks since Sirius's death and Harry had barely seen or talked to anyone, everyone was worried about him, including Tonks. With another sigh she put the mirror back in her cloak and knocked softly on the door.

"Go away..." A low pained voice replied.

Tonks felt her heart plummet upon hearing Harry's unhappiness. 'I have got to be strong... For Harrys sake'she told herself and then shook her head. She turned the handle and opened Harry's door. The light from the hallway sought out the darkness and drove it into the corners of the room as Tonks eyes scanned the room.

"Harry?" She quietly called as she stepped into the room, flickering on the rooms light as she turned to shut the door behind her before turning and settling her eyes on the figure lying on the bed. "Harry it's me, Tonks."

"Tonks?" Came the low pained voice from the huddled form of Harry, who was turning to face his visitor while putting on his glasses. The room came into focus as the glasses settled on his face, the bright haired female in his room became clear. "Tonks, what you doing here?" He asked.

She couldn't help but smile at his confused expression. "Wotcher Harry! Good to see you too." Came her cheeky reply, a slight grin crept up her face.

"I'm just surprised that's all, sorry."

Tonks huffed and gave a little pout then followed a smile. "I suppose I could let you off, just this once." She winked then tried to form a serious and straight face. "I'm here to deliver a message... And to see how you are, we're worried about you. Ron, Hermione, Remus... Me... And everyone else."

"Well you've had a wasted trip then, I'm fine... Although I'd be better if I wasn't stuck here for the summer!" Harry then scowled at the thought of having to put up with the Dursleys for the whole summer. He pulled himself up, to sit up in his bed as he looked at Tonks, watching her facial expressions.

"Oi, don't you go lying to me Mr Potter." She replied with mock seriousness, crossing her arms and trying her best to give a stern glare. "Don't you forget I'm a mighty Auror, I can tell when people lie and when people aren't ok." Then she dropped the pretend serious stance and softened her expressions. "And I'd be disappointed if you were fine."

Harry's confusion spread on his face at the last remark. "Disappointed?"

"Uh-huh that's right. Not being ok shows how much you loved my cousin; it's not something you should get over fast. Losing someone you cared for I mean. Time heals all wounds eventually... It's not something that can or should be rushed... At least that's what I tell myself every morning I wake up." 'If I'm lucky enough for sleep to find me that is...'

Harry didn't speak and instead just gave a small nod of his head to show his understanding as he looked down and peered at his lap, his confusion replaced with the sense of loss and grief.

Tonks gave him a moment to take in what she said, and to let the pang of grieve to retract. The same pang, that was now coursing through her body at the thought of Sirius. In the short silence that followed, Tonks took in her surroundings, much like the last time she peered into the room it was filled with clutter. 'Just how I like it' she thought as she reminded herself of her own living areas. Hedwigs cage was by the window with the snow white owl fast asleep inside, clippings from the Daily Prophet which displayed numerous articles referring to events over the past few weeks, spell books and quills were scattered over the desk along with a few photos. Harry's firebolt broom, propped up in far corner, Tonks couldn't help but admire it every time she laid eyes on the sleek finish.

"What's the message you had to deliver by the way?" Harry's voice snapped Tonks attention away from the room and back to him.

"Oops I nearly forgot" She rummaged through her pocket and pulled out a letter, looking back up she gave Harry a smile and strolled over to his bedside, tripping as she misjudged the height of a tome that was laying one floor, a frown followed by a blush crept back up her face and darkened in embarrassment at the show of clumsiness in front of Harry. Although this did manage to draw a smile from Harry's lips.

"Oh yes Mr Potter, very amusing." With a grin she handed the letter to Harry and sat on the bedside as he read it.

"Is this for real?" Tonks couldn't help but notice the underlying happiness and excitement in his tone and gave him a bigger smile. She knew the reason for this source of excitement, after maybe having a nosey at the contents. It was a letter from Dumbledore asking if Harry would like to spend the rest of the summer at The Burrow.

Tonks cocked her head. "Is what for real? I'm a very not-so nosey person, I have no idea what the letter says." Her face displayed the picture of innocence, even going as far as to change her hair to an angelic shade of white which then grew in length and flowed down her back.

Harry couldn't help but laugh at her answer and expression as well as her physical shift. "Yeah right, ok Nymphadora." His laughter grew as he received a whack on the arm for the use of her first name.

Tonks pouted. "You know not to call me that! And I don't like what you're implying. I'd never read someone's private correspondence. Not lil 'ol innocent me." She pulled a sad face, trying to suppress the giggles rising up inside her. Her little act seemed to work when Harry stopped laughing and seemed ready to apologize, before he could Tonks then went on to say. "So what answer should I give Dumbledore?"

They both broke out laughing and continued to do so for a fair few minutes, both enjoying the first true moment of happiness either had experienced since Sirius's death.

"Tell him yes, absolutely, most definitely yes!" Harrys answer didn't lack for enthusiasm, giving Tonks a big smile along with his reply.

"Really? I was sooo sure you'd say no!" She said jokingly and rolled her eyes which earned another chuckle from Harry.

"Thanks Tonks, for everything." Harry said after he stopped chuckling away.

Tonks raised an eyebrow. "All I did was delivered a message." She said with a hint of suspicion.

Harry shook his head. "Not just for that... For, I don't know... For not tiptoeing around me and for making the world seem and feel just the little bit less dark..." He gave her a smile then sighed. "I miss him, can't help but blame myself..."

Unsure of what to say at first, Tonks let her instincts take over and placed an arm around Harry and pulled him into a hug whilst positioning herself against the head board of the bed. She couldn't help but to give him a tighter hug when she felt how cold he was, or was she the one who was cold?

"Harry... I miss him too; he was one of the few family members I have that didn't try to kill me on sight..." She let out a sigh, 'Hmm maybe not the best way to swing the conversation, it reeks of Bellatrix...'she thought. "I grew up with him ya'know..." That statement brought Harrys head up to look at her prompting Tonks to go into more detail.

"Well he was already a young adult when I was born but he helped my parents raise me, mum liked the idea of her favourite cousin around, being one big family... She took him in when he left home, both disowned by the Black family, both in the same boat; they looked out for each other... Hmm maybe a story that I should save for another day, I want to show you something regarding that..."

That idea brought another smile to her face. 'Yes he'd like to see that, maybe for his birthday...'

"But know this Mr Potter! It's not your fault so don't let me hear you saying that again! Or you'll fall victim to my amazing Auror powers!" Tonks let out a small chuckle and smirked, a forced smirk. Deep down she blamed herself for what happened, 'If Bellatrix hadn't overpowered me…'"What you did... He would of been so proud of you, so would your parents of been. I know I am... You're turning into quite a remarkable young man and we are all so very proud of you and... And… Harry?"

She had only just peered down after her ramblings to see Harry fast asleep against her chest. 'Ohh awkward... And embarrassing! Oh no I hope his Uncle don't find us like this...' She couldn't help but blush at the situation, her on his bed with him nuzzled against her chest.

'I should wake him and go... Yes that would be the correct thing to do...' She thought about it then shook her head. 'Correct thing to do... When have I ever done that?' Tonks snorted at the very idea. 'It can't harm to let him sleep can it? He looks so peaceful; I bet the most peaceful he's been in weeks... Who am I to deny that after all he's been through? And why am I laying here having a lengthy conversation with myself when I've already made my mind up?'

That brought another sigh from her lips. 'As long as I don't fall asleep and leave the second he's moved off me, no harm done.' She smiled down at him, "Sweet dreams Harry."
