So You Think Your Sister's a Vampire? — I.D. Johnson

Don't trust anyone, not even yourself….

You think you know someone pretty well, until you're awoken in the middle of the night to the sound of unfamiliar voices and realize your sister's being swept away by some supernatural creatures who climb in and out of windows and leap from two-story houses like it's nothing.

My parents tried to tell me everything was fine, but when Cadence finally did come back from wherever they'd taken her, I knew there was something unusual about my older sister.

Now, her best friend is dead.

Her ex-boyfriend is acting bizarre.

And I'm afraid I might be next.

My name is Cassidy Findley, and I'm pretty sure my sister is a vampire, despite her “co-worker” making every effort to brainwash me into believing otherwise. With the help of my two best friends, we vow to get to the bottom of this before it's too late, and my sister starts to claim other victims. I love her, but I won't be turned, nor will I just sit by without doing everything I can to stop her. I can only hope that I'm not too late and that I can trust my own memories.

Because I'm pretty sure my sister's friends are coming for me next.

The Chronicles of Cassidy is a retelling of The Clandestine Saga specifically for young adult/teen readers told from the perspective of high schooler Cassidy Findley.
