Cal Kinsey's back on the beat, but nothing is the same.

After discovering a startling secret about his own history, Cal's been forced to split his time between honing new skills and healing old wounds. So when what appears to be a routine supernatural murder drags him out of the DSI office and onto the streets once again, Cal is initially overjoyed at the prospect of returning to some sense of "normal."

His hopes are dashed, however, when the seemingly simple crime suddenly morphs into a violent murder spree that leaves bloody bodies scattered across Aurora. With scant clues to the perpetrator's motives and identity, Cal and his teammates find themselves in a race against time to stop a magic practitioner hellbent on killing anyone related to a man that everyone at DSI was hoping they'd be allowed to forget.

But in the supernatural community, old wounds always reopen and old enemies always rear their heads again in the ugliest of ways. And while Cal now has more power at his disposal than ever before, the adversary pitted against him this time around may just be unstoppable. 

Spell Caster is the sixth book in the action-packed City of Crows urban fantasy series.
