Chamberlain is everything teenager Charlie Anderson thought it would be when he moved there from the city in 1957—a quaint and cozy upstate New York town where time moves slowly. But that’s all about to change.

Charlie finds his elderly and wealthy newspaper customer, Mr. Grazione, on the brink of death. Just before he passes, he shares a secret with Charlie. Grazione was part of a group of atomic scientists who discovered a special rock that allowed them to move through time. Harvesting the rock’s chemical—what they called Chronotine—they built a small device that could open a portal to the future. But in doing so, they sent off a cosmic alarm in the form of Pandora’s box.

A mysterious couple called the Travelers have arrived in Chamberlain and are searching for the rock. And they will stop at nothing to get it, including killing all the scientists associated with the Chronotine project. Grazione’s dying wish is for Charlie to destroy the rock. If he succeeds, Grazione believes the Travelers will disappear from their timeline.

But there’s a catch …

Grazione hid the rock in 1984, and there’s only a limited amount of Chronotine for Charlie to use to keep the portal open. If the device runs out, he will be trapped in the future
