Acclaimed author Kim Harrison returns this week with Black Magic Sanction, the eighth adventure in the New York Times bestselling "Hollow" series and her most complex and emotionally charged novel to date.

Bounty hunter-witch Rachel Morgan returns, this time trapped in a life-or-death battle against her own kind. Rachel has fought and hunted vampires, werewolves, banshees, demons, and other supernatural dangers as both witch and bounty hunter-and lived to tell the tale. But she's never faced off against another witch until now. Denounced and shunned for dealing with demons and black magic, her best hope is life imprisonment-at worst, a forced lobotomy and genetic slavery. Only her enemies are strong enough to help her win her freedom, but trust comes hard when it hinges on the unscrupulous tycoon Trent Kalamack, the demon Algaliarept, and an ex-boyfriend-turned-thief.

"I wouldn't miss a Kim Harrison book for anything," says Charlaine Harris, author of the Sookie Stackhouse novels. io9 has a preview of Black Magic Sanction below, and you can browse more inside the book here.
