If you look at Skylar Alender you'll see the typical popular girl, that has so many friends you'll lose count. Pale, beautiful, skinny, brunette, intelligent, confident, sweet, popular, brave, and bubbly is the way everyone at school describes her to others. At home she's another person, she's clumsy, cowardly, and easy to break. In her neighborhood, Skylar is known as the youngest, deadly, undefeated and heartless one. She's killed hundreds of people since she was seven, she gets nightmares every night about killing. But in her room, all she really is, is a quiet, extremely poor, broken girl. Then her mother gets a new job in Arizona, and all of a sudden she's a new foreign student with a dark past.
