Blood Warrior - H D Gordon - Bog

My mother trained me to kill, I just never knew why.Until now...Turns out, vampires, werewolves, and every creature of myth is real.The question is, why are they after us?All I know is I have to protect my little sister. At all costs.But the hidden academy we find ourselves in is not what it seems, and we have no idea who we can trust.We ran here for safety, but will we make it out alive?
