A Huntress For A Mate

Cleo seemed like a normal teenage girl, went to high school, had friends, even lived by herself.
But no, she is a huntress, of werewolves and vampires, there are sirens or mermaids if you wish but hunting them is a suicide mission that and she can't swim
she only lives by her self becuase vampires killed her parents and her older brother so now she hunts them, but she is fond of werewolves most only try to protect there pack or family while others, rouges just like to kill. most don't belive they are capable of love but she nows they are they are called mates. she doesn't kill werewolves often unless she has to but vampires, all they want is blood they don't care if there victim has family or if the victim is 8 they just want blood.
after moving to Chicago 1 year ago she starts to have a normal life other than still being a huntress with no one knowing but what happens when she finds out she is mated, to an alpha.
