In a futuristic world the entire society is built around memories being sent back from the future. On their 17th birthday everyone will receive a memory that will help sculpt who they will be in the future. When Callie receives her memory, it isn't one of her changing the world. Callie is gifted with the vision of her murdering her younger sister, Jessamine. Arrested for a crime she has yet to commit Callie finds herself brutalized and held in the hell that is known as Limbo, a place where they keep people whose vision shows them breaking the law. While being held, Callie is tested on and finds out that the government are holding, torturing, and then making these people live out their vision. Once they are forced to commit their crime they are killed. This is the fate in store for Callie, but it's so much worse, because if the government finds out that Jessamine is gifted, they'll take her and do tests on her. Callie is saved from her fate though by Tony, a boy she knew years before. Tony helps break her out of prison and takes her to a camp of outsiders who have each run from civilization and the future memory they were given. But running doesn't change the future and Jessamine is still taken and tested on by the government which sets off the motion of Callie returning to the city, but will Callie save her little sister or be forced to complete her memory of the future and kill her?
