Welcome back to Castle Rock, Maine, the fictional town that King has used as a location for strange events and even stranger people. It’s 1974, and Gwendy Peterson is 12 and trying to lose weight before middle school begins by running up the rickety stairs to Castle View. On her way down, she meets an unusual stranger who presenters her with a button box. Only, in true King fashion, this is no ordinary button box. By pressing one lever, a chocolate appears; depress another and a silver Morgan coin pops out; other buttons are tied to various locations around the world and have special powers. Gwendy is entrusted with keeping the box safe, and that isn’t an easy task.
