LIBRO USADO. SLOANE is a straight-A student from a loving home. MAGGIE is a glamorously independant up-and-coming actress in New York. TWO girls who couldn't be more different - except for one thing. At night, they dream they're each other. They live each other's lives, they know each other's secrets. But their two lives have never converged - until now. WHICH LIFE IS JUST A DREAM? WHICH LIFE IS REAL? Eventually, they will have to choose one life to wake up to, or risk spiralling into insanity. But for one girl, that means giving up everything - her life, her perfect love, herself - just when she finally has something worth holding on to.
