World of Legends by Sarah K L Wilson

When you don't know the rules, how do you play the game?
Tor Winespring never asked to be a hero, but now that he's been marked as one, he can't avoid a series of trials. At stake? The lives of all his friends and his beloved dragon, Saboraak. 
But Tor doesn't know the rules and his usual impulsiveness is nothing but a liability here. Can he slow down and figure out the puzzles before it is too late?
