The General and the Horse-Lord by Sarah Black.

The Knowledge Effect
Sometimes the truth hides in plain sight, invisible unless someone wants to see it. But once it’s seen, it refuses to be ignored.
When Martus and his sister Elsaben befriend Hal, a dragon, they realize what they have been taught growing up doesn’t match their experiences. The more they adventure together, and the more diverse people and magickal beings they encounter, the more they learn that life is rarely black and white. But getting others to let go of ingrained prejudices might be the toughest mission they’ll face—and they can’t fail, because each of them has a part to play in reshaping their world.
