Callie Michaels isn't pretty or popular, but her singing more than makes up for all she lacks. And as long as she focuses on what's really important, she can survive high school. But how can she focus with all the drama? Between her best friend's odd issues and a daily dose of weirdness from the social elite, she's starting to wonder if she's the only normal one around. He pulled the front door open. "That's how it's done." I rolled my eyes and made my way through the crowd that had spilled into the hall, muttering. "That's how it's done. Yeah? Where? In the jungle?" "Yeah." James' breath on my nape sent a chill down my spine. "Something like that." Just as her life begins spiraling out of control, the answer comes to her in a dream. In exchange for a token of blood, a demon will give her everything she desires. She says "yes." From that point on, she finds herself changing, becoming something far from normal. Something dangerous. No one is what they seem-least of all her. While the supernatural creatures around her struggle to maintain their humanity, Callie slowly loses hers. She doesn't even know what's important anymore. Friendship, the future, love? And is there anyone who can make her care?
