With her vampire side more or less under control, Alex Bain had finally found some happiness, especially with Finn, the charming half-fae bartender, heating things up things in the romance department. But when a desperate letter from her ex, Lucas—a warlock with a shadowy past—arrives, her fragile peace is shattered. Unable to abandon him, Alex sets off for Brazil with her bonded mated and the snarky demon Corgi, Argo, to rescue Lucas's sister from the clutches of a ruthless vampire Master.

Through the wild and colorful streets of Sao Paolo and the lush jungles of the Brazilian countryside, the group gains new allies and faces nightmarish monsters at every twist and turn. With every step, they all grow closer; even Argo stops giving Lucas a hard time, and Alex finds herself torn between her unresolved feelings for the fire-wielder and her deepening love for Finn. Then, when a desperate escape uncovers a sinister prophecy binding the three of them, Alex must confront the true source of her growing power and passion—one darker than she ever imagined.

As unforeseen betrayals and revelations cloud the path and threaten those she loves, will Alex’s heart guide her to a new destiny, or will it lead to catastrophic consequences? Can she master the darkness within, or will it consume them all? And does a girl really have to choose?
