For Breed vampire Trygg, a menacing former assassin and the ultimate loner, duty is everything...until his solo mission to destroy a powerful enemy earns him an unwanted partner in the form of Tamisia, a beautiful, ice-hot immortal who ignites a flame in his cold heart, and his blood.

Banished from her Atlantean colony, disgraced immortal Tamisia longs for a chance to redeem herself and return home where she belongs. Her work at a Rome women's shelter has given Sia purpose, but when a break-in results in a brutal killing, her quest for answers puts her in the middle of the hunt for a dangerous enemy of the Order--and brings her up against one of the deadliest of their Breed warrior members, the Gen One vampire, Trygg.

A former Hunter enslaved to the commands of a madman, Trygg has devoted his life to the Order. Duty is his only master now, until an interfering beauty inserts herself into his investigation. The last thing Trygg wants is a partner in his mission, but Sia will not be denied--nor will the fierce desire she stokes in him. Soon the warrior who needs no one is craving the only woman he should not desire, unleashing a powerful hunger in his cold heart, and in his blood.
