The Secrets of the Moonstone Heir — A.R. Cook

Desert Rain is an heir to one of the Salamandrian Sages, the Moon Dragoness, who with the other Sages formed the land of Luuva Gros centuries ago during the Great Manifestation. She has inherited the dragon's mystical powers, but she refuses to ever use them, making her fearful to interact with the outside world- that is, save her friend Ayu, a Wretched who has lost his memories and has slowly been recovering in Desert Rain's care. 

He is a Wretched. A curse to everyone, and he embraces it. 

When Desert Rain suddenly stumbles upon Ayu's lost memories and returns them to him, the Wretched's true nature is awoken: he is a Distortionist with an insatiable drive to not only destroy the clan that betrayed him, but transform all of Luuva Gros into his twisted vision. Desert Rain, feeling responsible for her friend's shift to madness, pursues him to stop the spread of his Distortion. With the help of a lizard disguised as human, a Quetzalin bird girl, and the mighty Swordmaster, Desert Rain begins a quest unlike any she's ever faced that could change Luuva Gros and everyone in it forever.
