Who Wants to Be a Vampire Hunter?

Secrets are like a spider's web, impossible to untangle....My older sister Cadence has just embarked on a clandestine life, and no matter the questions I ask, she refuses to let me in. Now that her ex-boyfriend is dead, it's time for me to discover the truth--even if I have to go behind her back.
Luckily, her new friend Elliott has been willing to reveal pieces of this secret world, one inquiry at a time. But the more he discloses, the harder it is to believe any of this could possibly be real. Vampires exist? There are other creatures whose sole purpose is to destroy them? Which side is my sister on-and what can I do to prevent anyone else from dying?
My name is Cassidy Findley, and the more I learn, the more certain I become that it is my destiny to become a Vampire Hunter, even if that means hunting my own sister. I will find the truth-one way or another.
