Dragonslayer

"Ivy doesn't trust the Dragonslayer. He may be her father and the beloved ruler of Valor, but she knows he's hiding more than the treasure from the sand dragon he killed two decades ago. Leaf doesn't trust dragons. They're the reason his favorite sister, Wren, is dead, and now he'll do whatever it takes to slay even one. Wren doesn't trust anyone. She swore off humans after her village tried to sacrifice her to the dragons. She only has one friend, a small, wonderful mountain dragon named Sky, and they don't need anyone else"--Dust jacket.
