Bred to believe in the war between angels and demons, Gabby has come to the conclusion that love is responsible for war, jealousy, and all the other deadly sins she can think of. So when she’s exiled to the middle of nowhere for getting kicked out of her fifth school for fighting, she doesn't expect to meet Jake. Much less fall in love. But Jake is quickly drawn to the eerie beauty of her violet eyes while Gabby is unsettled by their undeniable connection. When a demon guardian comes to collect her soul, she refuses to give it up. She’s not a demon. She can’t be. Her father and twin brother are angels. The demon gives Gabby twenty-four hours to decide her allegiance, and then starts killing her short list of friends, leaving a message behind: She is the Second Sign. As Gabby and Jake begin to unravel the mystery behind the Second Sign, she learns Jake may be the key to saving her soul. But it means a sacrifice has to be made that will change their lives forever.
