The screech of tires brought Hannah Scotts world as she knew it to a devastating end. A year after she signed the papers to donate her daughters organs, Hannah is still reeling with grief when she unexpectedly stumbles into the life of the Bell family, whose fifteen-year-old daughter, Maddie, survived only because Hannahs daughter had died. Mesmerized by this fragile connection to her own daughter and afraid to reveal who she actually is, Hannah develops a surprising friendship with Maddies mother, Olivia. The Bells, however, have problems of their own. Once on the verge of leaving her wealthy but abusive husband, Olivia now finds herself bound to him in the wake of the transplant that saved their daughters life. Meanwhile, Maddie, tired of the limits her poor health puts upon her and fearful of her fathers increasing rage, regularly escapes into the one place where she can be anyone she wants the Internet.
