Possession. Demonic infestation. A catastrophic collision of worlds held back by a fraying thread.

Join fantasy's boldest new heroine for her finest hour.

Kate Finch imagined she could author her own fate--become the indispensable apprentice, the loyal friend, the master of her witchcraft. Now she doubts everything. Her mentor August Swaine has no patience with her. Everyone she's trusted with her secret is under surveillance by the new governor, a man nursing a deadly obsession with Kate. And her witchcraft bends to its own will.

What she never imagined was that Swaine would start showing signs of demonic possession, the dark bane of sorcery.

While she covertly gathers evidence, she discovers Swaine has been hiding more from her than she feared. The link between his lies and the cataclysm threatening the colony terrifies her. Worse, Swaine turns on her, one step ahead of his uncertain apprentice.

Her one chance to stop the unfolding disaster means betraying Swaine. Turning to the very people who've wanted to see her locked away. Venturing into the treacherous halls of midnight in a last, desperate gamble.

Kate's fierce will has saved her time and time again.

But have her own doubts clouded her judgement? Can she outwit the infernal in the face of her entire world falling apart? Or is she out of time?

The trilogy races to a breathtaking ending in The Halls of Midnight, where searing choices collide in this unforgettable tale of witchcraft, sorcery, and magic.
