AN: Harry Potter and NCIS are two of my obsessions and what better thing to combine the two!

The timeline deviates for both the worlds and Harry is 20 years younger than Ziva, making her about Lily's age.

The characters will be OC or OOC (no review like in your dreams; its fan fiction, of course it's my dream.)

If anyone is interested for being a Beta for this story, please PM me.

Hope you like it. Please Review!

Prologue (I)

Ziva groaned when she heard the beep of her satellite phone. She had just returned after completing her mission and was desperately in need of some sleep. Changing time zones really screwed her sleeping pattern and whatever morsel of time she could dedicate to it was sacred. But knowing that only few people have that number, she knew it would be important.

Seeing that it was a London area code, she was puzzled. Only one person had her number there and for him to call her, something must be terribly wrong. Bracing herself because how can a call at 0300 hours be anything but a bad news.

"Shalom Prince", she said answering the phone.

"Ziva! Thank God you answered. I was not sure you would, not knowing whether you would be free or in the middle of one of your missions" replied Prince.

"Luck is with you my friend, I just returned from one and what would you know, I am in London myself. Now what can I do for you?" asked Ziva.

Ziva could hear the large breathe he exhaled over the phone. Something must truly be wrong for him to show any reaction like that. She had known him for a long time. He was her only friend who was totally unrelated to her line of work. She had been 5 and was visiting London with her mother where the two of them had meet Prince and his mother. The friendship has stuck even when he had left for his "special" boarding school. Prince had told her about magic when he had gotten his Hogwarts letter and being in her line of work earned a security clearance which allowed her to be in touch with witches and wizards. She knew about the wizarding war going in Great Britain. The security agencies were keeping a watch on it and if continued for a bit long, the matters will be taken out of the wizarding government's hand. Ziva depended heavily on her gut and right now it was telling her that whatever he was going to say, her life would never be the same.

"A few hours before, Lord Voldemort was defeated by the hands of one Harry James Potter, a 15 month old baby wizard. He was killed when he threw the killing curse at the boy and some form of protection from the boy's mother saved his life and deflected the curse back at him. His parents were killed in the process" answered Prince.

Ziva contemplated her answer before saying anything. "Okay. Where do I come in?"

"His mother is, was Lily Potter nee Evans."

"I am sorry for your loss brother" replied Ziva, aware of his feelings for the now dead witch.

"You know I was working as a spy for the headmaster and I have heard about his plans for the young one. He wishes for Harry to be placed with Lily's sister Petunia and her family" continued Prince, pretending not to hear what Ziva said.

"But is not her sister non magical and was not there a mutual dislike between them?"

"He believes that Voldemort will return and in the mean time the death eaters will want to harm Harry, for he killed their Lord. He is setting blood wards based on Lily's blood which will help in protecting Harry."

"Okay, but you are not coming to the point. What can I do?"

" I may not care very much for the elder Potter but I made a vow on my magic to protect Harry if anything were to ever happen to Lily. "

"And you think something will happen to Harry at his aunt's house."

"You know what happens to young wizards when they are left with narrow minded bigoted muggles "replied Prince.

Ziva was aware. Completely, remembering his father and his aversion to all things magic, including his son and then later his wife.

"Dumbledore will leave Harry at his aunt's house in about 24 hours. He will drop him off at the front step of their hose which will activate the blood words. I want you to take him and give him to people who will care for him and love him like their own and also protect and prepare him for his destiny, because senile fool he may be, Dumbledore is not completely insane and I agree that Voldemort will return to complete his work."

"Are you sure this is wise?"

"I trust you Ziva. Don't worry. I will make sure that he will not be able to track you or Harry. He will be none the wiser about everything."

Ziva would have said no but she owned him one. He had saved her life a year back when she had been poisoned and she knew that a life debt was a big thing in the magical world. She was also aware that he was not referring to it directly, that sneaky bastard.

"Okay. I will do it. I will find the sister and wait for the drop. After he is placed successfully, I will inform you."

"Thank you Ziva. Thank you so much. I will be in your debt"

Ziva could hear the emotions in his voice and knew he was on the verge of tears.

"You don't owe me anything brother, we are even. Shalom Prince, take care"

"Shalom Ziva, you too."

After dropping of the phone, he cancelled the silencing spell around the booth and returned to the alley side by. A cat, on seeing him came from the shadows and easily morphed into one Minerva McGonagall.

"Did she agree Severus?"

"She did Professor. Tomorrow she will be there to pick up Harry at Petunia's home."

"Can we really trust her?"

"I trust her with my life Minerva. She would not let any harm come to him."

"Then I shall take your leave. I will be keeping an eye on the Dursley's tomorrow. "

"Thank you Minerva, if not for you, I don't know what would have happened to Harry", replied the young potion's master, still emotional.

"They were my friends too, Severus. They would not want their son to suffer" replied Minerva, dabbing her eyes with the corner of her handkerchief.

"I will inform you of his placement. Good bye Professor" replied Snape and with that, apparated away before she could reply.

McGonagall also apparated away.

It was very easy to find Petunia Dursley's house in Little Whinging, Surrey. Ziva decided to reach there at around 0030 hours and await their arrivals.

After reaching there, she decided to get comfortable for the long wait. At times she was sure that there was someone watching her, but when she turned there was a cat there, calmly watching her. She paid no attention to her.

After watching the whole scene unfold, Ziva was a bit shocked, but that bike thing was really cool. She made a note to ask about it the next time she talked to Prince. She missed the women's entry but was not worried, they had a way of arriving anywhere out of the thin air.

When she was sure that everyone has left, even the cat, she made her way towards the front door where a toddler slept in the basket.

Silently picking up the baby, she dislodged the letter attached to his blanket and read it.

Huh stupid fool. He did not even bother to give full information to the people he left the child with.

As soon as she dropped the letter into her bag, the child woke up. For a moment, she panicked, babies did cry when encountering strange people. She was surprised when he only blinked and settled deeply in his arms. He seemed to be watching her and she was mesmerized by his clear forest green eyes. She then traced the harsh and angry looking scar and traced the lightning bolt shape. Harry took her finger and started to drool on it.

"Ahh, are you hungry baby? Let's get you settled"

Harry sighed and after a little shifting in her arms, was asleep once again. Ziva gently rocked him and placed a light kiss on his brow. She had never considered herself to be the mothering type but holding Harry felt as if it completed her. There was a warm and fuzzy feeling spreading through her and unaware to everyone, a golden bubble surrounded the two.

The ancient magic that saved Harry again bubbled and their relation was sealed.

Ziva knew what she had to do. She was not going to give Harry to anyone else. She was going to raise him herself.

Ziva returned to her car and gently placed Harry in the car seat. Straightening his blanket, she made a vow to her new son," Nothing will ever harm you Ha'ben sheli . It's my promise.

With that she drove into the night.
