Spirit

Valerian (Val) Howell has no intention of using the Spirit skills she was born with, until she stands over the body of another spirit worker at a murder scene.

At that point she has a choice.  It's either use those skills or get flattened, with the dubious help of an irritatingly attractive coworker-turned-bodyguard who just might be working for her enemies.

She's tangled in a web of memories that aren't even hers, fighting an enemy she can't see with weapons she's never taught herself to use.

Why can't anything dealing with Spirit be simple?
