Atone by Wendi Wilson

Vampires aren’t real…
Everyone knows that, but after a drug experiment gone wrong, a new generation of children share a frightening number of characteristics with the fictional bloodsucking monsters. Needing blood to survive. Advanced hearing capabilities. The ability to control people with their minds…
My name is Lizzie Williams, and I have spent the last several months being molded into a soldier for the Divine Church of Purity— a group of intolerant, bigoted people desperate to keep our species pure and untainted by Homo Altiorems, or Alts. They were created by man’s desire to play God, therefore unholy and a blight on humanity.
I can’t believe I ever bought into that load of crap.
Now, I’m doing whatever I can to right the wrongs I’ve committed. My journey to redemption takes me to Connecticut, where I meet Silas and Slade Madsen. Brothers. Twins. Insanely hot and one hundred percent Alt.
But that doesn’t worry me. Even if they don’t trust me, they can’t use their Alt powers against me, because I’m different. The Purist church made sure of that, giving me an injection that made me immune.
I’m Lizzie Williams, and I’m unpersuadable.
