Menolly D'Artigo, a vampire married to a gorgeous were-puma, is one of three half-human, half-Fae ex-operatives for the Otherworld Intelligence Agency. Caught in the middle between the devious plans of a malevolent necromancer and a soul-munching Sub-Realm leader, Menolly's challenges are just beginning. Her wife has been kidnapped, and unless Menolly and her sisters meet the enemy's demands, the were-puma beauty will die. To save her, Menolly must lead an army of vampires into the very depths of the Subterranean Realms.
