My name is Hannah. Sometimes my mind plays tricks on me.

As a quiet, true crime-obsessed teenager, I don't have many friends. With the exception of my tirelessly working mother, my father who lives far away, and my therapist, Dr. Psych, I'm alone. Until the day I met Rebecca.

Rebecca is everything a girl wants to be. Beautiful. Popular. Star of the cheerleading squad. When she takes an interest in me, I jump on the chance to be her friend. It doesn't matter that her boyfriend hates me, or that she is only friendly with me in secret. I'm lucky to have her, and we both know it. That is, until I have to learn the hard way. When things feel too good to be true, they often are.

When Rebecca goes missing, it's up to me to uncover why. Remember when I said my mind plays tricks on me? It also loses memories...and a lot of them. Where did Rebecca go? Why can't I remember anything from the days before she disappeared? And can I figure it all out before it's too late?
