But instead of jail time, Cole is given another option: attend Circle Justice, an alternative program that sends juvenile offenders to a remote Alaskan Island to focus on changing their ways. Desperate to avoid prison, Cole fakes humility and agrees to go.

Like his fellow lunarnauts - otherwise known as Moonies - living on Moon Base Alpha, twelve-year-old Dashiell Gibson is famous the world over for being one of the first humans to live on the moon.

And he’s bored out of his mind. Kids aren’t allowed on the lunar surface, meaning they’re trapped inside the tiny moon base with next to nothing to occupy their time—and the only other kid Dash’s age spends all his time hooked into virtual reality games.

Then Moon Base Alpha’s top scientist turns up dead. Dash senses there’s foul play afoot, but no one believes him.

Chase's memory just went out the window.

Chase doesn't remember falling off the roof. He doesn't remember hitting his head. He doesn't, in fact, remember anything. He wakes up in a hospital room and suddenly has to learn his whole life all over again... starting with his own name.

He knows he's Chase. But who is Chase? When he gets back to school, he sees that different kids have very different reactions to his return. Some kids treat him like a hero. Some kids are clearly afraid of him.

One girl in particular is so angry with him that she pours her frozen yogurt on his head the first chance she gets.

Pretty soon, it's not only a question of who Chase is - it's a question of who he was... and who he's going to be.
