This is a Challenge for a Harry Potter Once upon a time crossover. There is going to be slash between Harry and Peter Pan.
Harry didn't have an easy childhood. He was mad to work, belittled and beaten at every turn. So he dreamt. He dreamt of Neverland and one day, when he lay bleeding and nearly starved in his cupboard his magic bought him there.
Peter found him and healed his wounds. They became friends and Peter decided that he would protect his precious little Harry at any cost.
Together they discovered Harry's magic and learned to control it.
After that it is up to you.
Here are some things I demand though: Harry will never return to the magical world. And Peter Pan is not Rumpelstilzchens father.
I hope someone takes this up.
When someone decides to write this I will add another chapter, where I tell you who.
PS: I sorry for any grammar or spelling mistakes.
