Into the dark (Dark chaos series #1)

I have known how to kill since I was 5, to do a silent take down by 8, leave no evidence behind by 10.

Ryiah works for a secret society called the Dark Knights who specialize in killing the supernatural, although Ryiah has never actually seen one of these acclaimed "beasts" she's heard so much about she has grown up learning that these creatures are foul and dangerous. So when she finally has the chance to kill one of them she is surprised to learn that these "monsters" are harder to kill then she thought especially when they're gorgeous and alluring.

In a battle between right and wrong Ryiah just doesn't know what's good and what's bad especially when the bad looks so good.
