Frankie rolls into autumn by practicing her affinity--which drives her crazy--growing herbs for the coven garden-with a tiny bit of cheating--and building muscle tone--in case she stumbles across a dead body that needs lifting. Living with Ben and Cleo in her mother's old house is comfortable and she's the happiest she's ever been, but someone is missing.

When Frankie receives a message hinting at Jessamae's whereabouts, the coven--with the help of a familiar face--ships off to Las Vegas in hopes of finding Jessamae and prying her from the clutches of The Strip's ruling class.

After Frankie makes an enormous and violent mistake, she is taken by the Las Vegas Sovereignty and forced into servitude--fighting in the witch pits against opposing affinities. Ben hurls himself in harm's way to save her.

The coven's been blown apart, no one is safe, and Frankie blames herself. Maybe she should.
