The Lost Boy I - Vikings and dragons

What if Hiccup wasn't all alone before he found Toothless ? What if his tribe had found and adopted a lost boy with strange white hair ?

Hiccup only live to become one of his viking tribe. However, the day he is given the possibility to do so by killing the most dangerous of all dragons, he has to make a decision that will change his life forever.

This is a Hijack/ Frostcup AU. boy x boy. Don't like, don't read. English is not my main langage.
