A/N: For Amy, Katy and my mother, my biggest fans who shipped Luna/Neville from the start.

The Moon Wants Only For A Sky

Neville,

I don't when I'll see you again, or if I ever will. They took me away from the train, from my father. They took me away from you. I didn't get the chance to tell you what I've wanted to tell you since the night you saved my life in the Department of Mysteries.

You, Neville Longbottom are the reason I wake up every day with hope inside my heart. You're milk and cookies, you're strawberry ice cream with chocolate topping and you're hot chocolate with marshmallows. You're everything that I love, but that I know I shouldn't really eat.

Neville Longbottom, you are my comfort food, and if we ever make it out of this mess, I want to grow old with you. The call just came through, they're starting to fight. Hopefully, I'll be able to give you this myself, but if not, I want you to know that I love you. I always have, I always will. The last word on my lips will be your name.

Love,

Luna

Dear Luna,

Harry just arrived; we're getting ready to fight...

I'm scared. I don't know if I can make it...

I don't know what I'll do if I lose you...

I hope I don't have to find out...

Stay safe Luna...

I'm going to need you when this is over...

I'm going to need you for always...

You're my moon...

Love,

Neville

Neville Longbottom stood at his bench in the Great Hall, scanning the heads for the pale blonde he longed to see. Just as he spotted her- talking to Harry who swiftly disappeared behind his Invisibility Cloak- he began to feel very dizzy. She looked around at him just as he collapsed, falling to the floor. Looking up he could see stars, followed closely by her face. She looked at him with such urgency, such love that he wanted nothing more than to look at her forever. Before he was ready, his eyes drifted shut.

'Oh Luna' he breathed, succumbing to his exhaustion and pain.

Luna sat stubbornly beside Neville, ignoring Madam Pomfrey's demands that she leave. She reached over to brush a bit of hair off his face, the tiny cowlick that she knows he hates. As she hovers over him, she holds in her hand a piece of paper that fell from his pocket. As she read it, the rambling lines with no end, she found herself unable to breathe. She took the small, delicately folded piece of paper out of her own pocket and dropped it on his chest, then turned and ran out of the hospital wing, ignoring the cries from the Weasleys gathered at the end bed. She ran down eight flights of stairs, through several passageways until she reached the Entrance Courtyard. Once there, she fell to her knees, sobbing hysterically, not noticing as McGonagall followed her outside.

'Luna?' she whispered 'are you alright?'

Luna looked up at her favourite teacher, face smeared with dirt, save for the tracks of pale skin shining through.

'That was a stupid question' McGonagall said after a few moments of silence 'I don't think any of us will be alright for a very long time. Would you like to walk with me?'

The older woman held out an arm to help the younger stand and they struck off in the direction of the lake, walking in companionable silence for several minutes before Luna spoke.

'Why did you ask me? Why not a Gryffindor?'

'Because I had something I wanted to say to you.'

Luna stopped and turned to her favourite teacher. As McGonagall searched for the words she needed, the wind started to pick up, blowing Luna's long blonde hair across her face.

'This year has been hard on you, I can see it. Don't let it affect you, don't you dare crawl into your shell. Don't lose yourself because of this' McGonagall told her, gesturing towards the castle 'you are one of the strongest girls I've ever met. Don't let this become all of you. Use it to become stronger, but don't lose yourself along the way. Let yourself love him, now that you have the chance.'

McGonagall turned to walk back up to the castle, stopping after a few steps to shout over her shoulder.

'Luna? You should have been in my house, and if you decide to come back, you will be.'

Luna smiled and then stood on shaky legs, walking the long winding path back to the hospital wing, stopping on the way to Neville's bed to lay a comforting hand on George Weasley as he willed his little sister to wake up. She sat beside Neville's bed, taking his hand in hers and pressing it to her heart.

'Neville, wake up. Please. There's something I need to tell you. Neville, please.'

His eyelids flicked briefly, but he did not wake. Luna brushed away the few tears she'd shed then leaned over her friend's sleeping form, kissing him gently on the cheek.

'If I'm the moon, you're the sky. Please wake up, I need you' she whispered before returning to the Great Hall to help with the injured.

A/N: This is just a short introduction chapter. I'd appreciate it if you could let me know what you think. Please find a handy review button below. Maybe it was a bit cheesy to use the 'Luna' thing, but I think that's the way love works sometimes.
