Sea Glass - (Chronicles of Ixia #5)

Opal Cowan, glass magician-in-training, has discovered a terrifying and powerful new ability: she can steal the power of other magicians. And that makes her too dangerous to be set free. Ordered to house arrest by the Council, Opal defies them to search for Ulrick, the man she thinks she loves. But as she travels through the Moon Clan's lands, she begins to hear disturbing rumors that Ulrick's desire for blood magic has eclipsed any sense of reason--and perhaps even his passion for her.

Deep in hostile territory, without proof or allies, Opal isn't sure whom to trust. And everywhere she turns, people want to control her powers for their own deadly gain. Opal must make the choices to secure her own future, even as the path she treads becomes more dangerous than she could have ever imagined.
