Siren's Song. Aspect Society, #1

He's her best chance of surviving the nightmares that hunt her...if her unpredictable magic doesn't kill him. Siren Savage doesn't stay in one place for longer than six months. Nightmare creatures stalk her footsteps, and the man who controls them is hellbent on taking her magic for his own. Given the givens, a normal life isn't in the cards. But when she meets Jace Winters, she finds herself wanting everything she knows she can't have. Old wounds have Jace staying as far away from Aspect-the power that runs in his family's bloodline-as possible.
But when he meets Siren, he knows he's the only person alive well-versed enough in Aspect Theory to help her control her strange magic. He's incapable of turning her away, even if it means diving back into the very society he once swore he'd have nothing more to do with. Neither of them planned on falling in love, but you know what they say about the best laid plans...
