Novel Reflection Dragon Rider

  The book I just read is named Dragon Rider. It's a book about a dragon named Firedrake, a brownie(a magical creature) named Sorrel and Ben the human search for the Rim of Heaven that the dragons can live in peace forever. They got there but a monster in a shape of a dragon want to kill them all but they defeated him instead. The main characters in this novel are Firedrake, Sorrel, Ben(the dragon rider) and Twigleg the homunculus. Each of them has a different perspective of the world and different personality.
