14-year-old Charlotte Kente has been waiting to open her fourth grade letter ever since she wrote it back in September of 2015. Once she finally reads it, she realizes the shocking and sad reality that her 9-year-old self had to live in. Her only wish is to go back in time and fix the problems that her childhood self had in hopes that things would be different in the present. That far fetched wish comes true. Vowing to better and mentor her younger self, she spends weeks back in 2015 to do exactly that. When her blast from the terminates, she truly believes that she accomplished her goal. The whole project is either completely useless, or it might change her life. But can weeks in only one small portion of her life really change the present as much as she hopes?
