If I Were King

When Jigsaw/John Kramer realizes that yet another book about the "Jigsaw Games" has been written, he originally believes that it is about how someone survived from a trap they were never in, similar to some time ago- but it turns out that it's the exact opposite.
The book, written by college student Harlow Thomas, instead describes her thoughts about what would happen if she were to become a Jigsaw Apprentice, and how her "games" would work if she was the one in control.
Surprisingly intrigued by the mind of the young woman, Jigsaw takes Harlow on as his next apprentice, though she must prove herself along the way. While taking on traps and games designed just for her, she must have the mindset of both the victim and the mastermind.
But when it's ultimately time for her to take the reigns and finally follow in Jigsaw's footsteps, can she live up to his legacy just as she described in her book? Or will the throne she's built up crumble around her?
