Vampire Unleashed by Tamar Sloan

A vampire. A huntress. A cure that could change everything.

Vampires are real. If that’s not enough for Maddy to get her head around, then learning she’s a descendant of the famous Knights Templar, a secret order of vampire hunters, leaves her reeling. What’s more, they want her to join their ranks.

Thrust together, the two discover deeply buried secrets and shocking truths. The Order isn’t everything it claims to be. The vampire Master has plans to cultivate humans as a food source. And everyone is searching for an ancient relic that could be the key to it all.
And yet Maddy has questions that desperately need answers. Whose side is Caleb really on? What does she do about the attraction that won’t go away? And why does she seem to have abilities no one else does…
