The Dragon Boy (a HTTYD fanfic)

What if Hiccup lived his entire life with dragons instead of vikings? Hiccup Horrendous Haddock III, son of Stoick the Vast, had never known the comfort of man. His mother had been taken by a dragon before he could be born among vikings. Growing up in a isolated fortress with his mother and loyal Night Fury, Toothless, Hiccup learns what it feels to live as a dragon would. His whole world has been revolved around his mother and best friend. That world will change forever when Hiccup is thrusted into the Dragon-Viking war after a mysterious man attacks the only home he knew. Tensions will rise, bonds will be tested, and when Stoick discovers his long-lost son, Hiccup will have to make the ultimate decision: choose his own kind or live amongst the creatures he sought to protect.
