Emily Webb is a geek. And sheβs happy that way. Content hiding under hoodies and curling up to watch old horror flicks, sheβs never been the kind of girl who sneaks out for midnight parties. And sheβs definitely not the kind of girl who starts fights or flirts with other girlsβ boyfriends. Until one night Emily finds herself doing exactly that . . . the same night one of her classmatesβalso named Emilyβis found mysteriously murdered.
The thing is, Emily doesnβt know why sheβs doing any of this. By day, sheβs the same old boring Emily, but by night, she turns into a thrill seeker. With every nightfall, Emily gets wilder until itβs no longer just her personality that changes. Her body can do things it never could before: Emily is now strong, fast, and utterly fearless. And soon Emily realizes that sheβs not just coming out of her shell . . . thereβs something much bigger going on. Is she bewitched by the soul of the other, murdered Emily? Or is Emily Webb becoming something else entirelyβ something not human?
As Emily hunts for answers, she finds out that sheβs not the only one this is happening toβsome of her classmates are changing as well. Who is turning these teens into monstersβand how many people will they kill to get what they want?
