Here Lives a Corpse by C.L. Matthews

Life doesn’t promise anything but existence.
Losing Cass proved that.
Everyone thinks I’m crazy.
Corpse.
Freak.
Vampire.
They called me the one who never overcame the loss of her brother, the outcast, the least likely to succeed.
But what about their lies?
He jumped. He wanted to die. He killed himself.
When will they stop?
Unraveling the secrets they founded this town with seems impossible.
Detangling the bloodlines that weave the very essence of Arcadia Crest might actually kill me.
Forgetting the little details I’ve erased from my memories as a result of love could be the catalyst of my entire story.
Death brought me hatred.
Hatred drove me to them.
They touched me only in secret.
All stories end in blood, but an oath was never part of that equation.

Here Lives a Corpse is book one of a five-part series. You do have to read all to understand. Each one ends on a cliffhanger.
