Karlyssa has trained all her life to be a Shadow Slayer. She's 17, leading a team in Washington D.C. She's the youngest team leader there's ever been and it's the only job she'll ever hold. That's fine with her as long as her teammates and friends aren't bound to her same fate. On the night of her best friends Shabdkosh ceremony, a warlock Valour is killed and the barrier between the human and demon world is breeched. Karlyssa thinks nothing of it except for another case to solve. However, the more she finds out the more questions she has about why this is happening and how to stop it. There's one person that can help her, but accepting help means risking more than she ever bargained for. Will Karlyssa be willing to risk the lives of her teammates and her humanity in order to restore order to the world? Or will she risk something even greater instead?
