Sammie McCoy is a girl with a plan: graduate at the top of her class and get out of her small town as soon as possible. Nothing will stand in her way--not even the rare genetic disorder the doctors say will slowly steal her memories and then her health. So the memory book is born: a journal written to Sammie's future self, so she can remember everything from where she stashed her study guides to just how great it feels to have a best friend again. It's where she'll record every perfect detail of her first date with longtime-crush Stuart, a gifted young writer home for the summer. And where she'll admit how much she's missed her childhood friend Cooper, and the ridiculous lengths he will go to make her laugh. The memory book will ensure Sammie never forgets the most important parts of her life--the people who have broken her heart, those who have mended it--and most of all, that if she's going to die, she's going to die living. This moving and remarkable novel introduces an inspiring character you're sure to remember, long after the last page.
