Monsters are evolving. Their happy ending is imploding. And now they're in a race to outlive a deadly bargain with the enemy...

Vee Ramirez is used to making sacrifices. So she takes it in her stride when a routine trip reveals strange behavior among the cryptids she was born and bred to fight. But after she stakes a rogue vampire, she's shocked to discover her handlers have been toying with using the bloodsucker's virus on their own agents.

Bruce Kantor doesn't trust easily. But since he's wildly loyal to those he lets in, the abrasive chef reluctantly agrees to his kickass fiancée's request to see a doctor about his nagging cough. And when he receives a devastating diagnosis, he's determined to wring every drop of joy out of his remaining days with the brilliant beauty.

Diving deep into forbidden research, Vee exposes herself to the fanged undead in the hopes of discovering a new treatment. But while Bruce scorns her blind faith in her superiors, he fears she's about to violate everything she believes in and do a deal with the devil.

With mutations and blood flowing through the streets, will their passion survive?
