About the Book
She was a century-old immortal enforcer who felt nothing. He was a ruthless cartel king who controlled everything. Their collision was bound to be fatal.
Seraphina Thorne has survived a century by adhering to two rules: trust absolutely no one, and never break the Blood Oath of Purity. As an elite Enforcer for the Vampire Council, she is cold, lethal, and undeniably efficient. But when a rogue faction of bloodsuckers infringes on the territory of the city's most dangerous mortal, Sera's routine cleanup mission erupts into a violent turf war.
Alejandro Vargas, known on the streets as El Diablo, built his cartel empire on the bones of his enemies and the absolute certainty that mercy gets you killed. When he discovers a deadly, ancient predator operating in his sanctuary, his first instinct isn't to run — it's to claim her.
When a brutal attack forces them into a bloody alliance, Sera takes Alejandro's blood, binding her soul to a mortal. Now, the Vampire Council's Vanguard is at their door with iron, silver, and fire. Visceral action, dark romance, explosive chemistry, urban fantasy mafia crossover. Morally gray, high-heat.
