Guardian by K. L. Hernandez

A half-human with a secret. A vampire with a plan.

In the new world where vampires rule alongside humans, Katerina Eli is a guardian in the Company of Essential Guardianship, a protection service for both species. When she receives an offer to protect a Regal Vampire Family, Katerina accepts the opportunity to put her past behind the CEG’s walls and subdue the beast that rampages deep within her. But what seems like a miracle never is.

Cast away from society, the Sephtis brothers are heirs to the Premier title, head of the Vampire Ministry, and ruler of their species. Besides their shared birthright, they hold one common interest: to take revenge against the father who drove their mother to her grave. When Alek Sephtis, the fourth oldest, is tasked to get rid of the new guardian, he’s granted the upper hand to end these petty retributions. Yet one’s plans can never quite go accordingly.

Bound by maintaining peace between their species, Katerina’s and Alek’s unlikely alliance will uncover more than they bargained for. Their blossoming attraction will resurrect buried lies. The future of a ruling title will dictate their end. And a monster will be their ultimate demise.
