My life as a small town high school student would soon be transformed as I discovered an entirely different world, one where Vampires, Guardians, and Hunters war over humanity.

So You Think Your Sister’s a Vampire?–Book 1
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.
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.  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.
Who 
Wants to Be a Vampire Hunter?–Book 2
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.
The more I learn, the harder it is to believe any of this is real. Vampires exist? There are other creatures whose sole purpose is to destroy them? 
Now, I’m certain that it is my destiny to become a Vampire Hunter. I will find the truth—
one way or another.
How Not to Be a Vampire Hunter–Book 3
There are some mistakes in life you can never recover from….
Have you ever wanted something so badly, you’d do almost anything to get it? That’s how I feel about becoming a Vampire Hunter. Even though I’m technically not old enough to go through the transformation process, I’m ready to fulfill my destiny—
one way or another.
Unfortunately, going behind my sister’s back  doesn’t go as planned, and before I know it, I’m no longer a would-be hunter; I’m the prey.
Now, all I can do is hope that my sister and her teammates can get to me in time or else my career as a Vampire Hunter will be over before it’s even started.
And so will my life.
My name is Cassidy Findley, and I’m about to find out the hard way how NOT to be a Vampire Hunter.

Sometimes following your dreams isn’t all it’s cracked up to be….

There’s a dangerous Vampire on the loose, and I know I’m the only one who can stop him from continuing to prey on the innocent. But since I’ve already broken my sister’s trust, how can I prove to her that I’m more than just her little sister? 
I’m a weapon.
