It shouldn't have taken me this long to recommend "How To Train Your Dragon", the amazing book (and the beginning of a series of stories) by Cressida Cowell.
Okay, I know you've all probably heard of this book already. I mean there's been movies and a Netflix spinoff, but the book is awesome in its own right, and deserves its own mention.
Hiccup Horrendous Haddock III is a young Viking who isn't very good at all the heroic and bloodthirsty stuff that Vikings are famous for. He prefers to think things through and study, neither of which are particularly vikingish traits.
Because of this, Hiccup has a different approach to dragons. While the other Vikings try and subdue dragons by shouting at them and being generally unpleasant to the beasts, Hiccup learns their language, talks to them and soon becomes an expert in all things dragon. The other vikings think he's ridiculous until a dragon arrives that they are simply unable to bully.

Watch out dragons... Here be Aaron!
Aaron is a brat, which is understandable after everything he's been through. He also sees dragons when he hums, which isn't understandable by anyone, ever. He soon gets sucked into the dragons' dangerous war, where his only defences are his embarrassingly magical fingernails, and a fierce, ten-year-old girl.
