Welcome to Nocturne City, where werewolves, black magicians, and witches prowl the streets at night…Among them is Luna Wilder, a tough-as-nails police officer whose job is to keep the peace. As an Insoli werewolf, Luna travels without a pack and must rely on instinct alone. And she's just been assigned to find the ruthless killer behind a string of ritualistic murders—a killer with ties to an escaped demon found only in legend…until now.But when she investigates prime suspect Dmitri Sandovsky, she can't resist his wolfish charms. Pack leader of a dangerous clan of Redbacks, Dimitri sends her animal instincts into overdrive and threatens her fiercely-guarded independence. But Luna and Dimiri will need to rely on each other as they're plunged into an ancient demon underworld and pitted against an expert black magician with the power to enslave them for eternity…

    The trip takes an even nastier turn when they discover the true nature of the nefarious plot they've been drawn into. On the wrong side of the vengeful cat goddess Bast and chased by an unfathomable number of her yowling four-legged disciples, Atticus must find a way to appease or defeat Egypt's deadliest gods - before his grimoire-grabbing quarry uses them to turn him into mincemeat.
