In the third book of the Fever series from #1 New York Times bestselling author Karen Marie Moning, a woman explores the limits of her mysterious powers as she enters a world of ancient sorcery-and confronts an enemy more insidious than she could ever have imagined.

He calls me his Queen of the Night. I'd die for him. I'd kill for him, too.

When MacKayla Lane receives a torn page from her dead sister's journal, she is stunned by Alina's desperate words. And now Mac knows that her sister's killer is close. But evil is closer. And suddenly the sidhe-seer is on the hunt: For answers. For revenge. And for an ancient book of dark magic so evil, it corrupts anyone who touches it.

Mac's quest for the Sinsar Dubh takes her into the mean, shape-shifting streets of Dublin, with a suspicious cop on her tail. Forced into a dangerous triangle of alliance with V'lane, an insatiable Fae prince with lethally erotic tastes, and Jericho Barrons, a man of primal desires and untold secrets, Mac is soon locked in a battle for her body, mind, and soul.

As All Hallows' Eve approaches, the city descends into chaos as a shocking truth about the Dark Book is uncovered, and not even Mac can prevent a deadly race of immortals from shattering the walls between worlds-with devastating consequences.
