Winnie's six-year-old stepbrother, Mikey, jumps through a time tear. Fearing he'll fall prey to the dangers of an unknown alien world, she and their friend Kip follow. The pair land in a rural walled-off community with a reputation for banishing outsiders. To their horror, Mikey is nowhere to be found, but at least Nor, the son of a lord, agrees to hide them. For a price. He'll join their search for Mikey provided they help him recover Kinny, a little boy Mikey's age who has accidentally fallen through a different time tear. Can the three teens find the young boys before the Reserve Guard tracks them down?
