Never Call Me Vampire - Legends of Crimson Hollow, #1

The world calls him vampire. But that's not who I know. He's my fellow patient at Crimson Hollow, a facility for those infected with the vampire virus. He's lived for more than a century and has been called many things. Vagabond. Circus freak. Prisoner. Murderer. Now he's the world's most famous person. He receives blood transfusions to stay conscious and rarely leaves the facility. He'll never be free.
Except in death. And that was what he wanted.until I arrived. All I wanted was a cure. I wasn't planning to fall in love. He knows too much about my secret. And I've learned too much about his past. Someone is planning to unleash a serum that will destroy the entire world. But to save everyone else-we must sacrifice ourselves. They call him vampire. But only he knows his true nature. And I may never be prepared to accept it.  "This book made me want to believe in the unbelievable!" -Angela Larkin, co-author of the bestselling Beyond series
