Vampires and Violas by Shari L. Tapscott

Hi, I’m Piper Edwards, and I’m pre-vampiric. Don’t worry—it’s not as bad as it sounds. Right now, my love life is far more complicated than my diet. Taking prescription blood three times a day? Easy.
Abstaining from nibbling on Noah’s yummy neck? Not easy.
You know what else isn’t easy? Tracking down Cassian’s hundred-year-old ex-girlfriend, learning how to properly use a stake, and figuring out how to tell my parents I’m now a creature of the night.
But honestly, I don’t think anything could be worse than suffering through vampire support groups…until my ex-stalker’s favorite assassin decides to pay me a visit.
