"There are some weird stories about that locker. They don't usually let kids have it."
After her mother commits a terrible crime, Misti is sent to live with her estranged Aunt and Uncle. Welcomed with open arms, Misti finds herself in a safe place for the first time since she can remember. She struggles to navigate life around her cousin, Penny, new friends and the handsome boy in her art class. On top of all of this, Misti is assigned Locker 31, the haunted locker. Misti dismisses the stories. Ghosts aren't real.
When her things are arranged for her classes, Misti suspects she is being pranked. When her lock is spinning, she blames lack of sleep.
When a 20 year old diary appears not only giving life to the odd occurrences at the locker but brings them to her home, she runs out of explanations. With the help of her new friends, Misti sets out to solve The Haunting of Locker 31.
