They are the perfect family. But perfection is fragile.

Cal Hudson knows the world can be an ugly place. As a reporter for a big Chicago newspaper, Cal has journeyed into society's darkest corners to expose the vilest crimes. But the world he and his devoted wife, Faith, share with their son is much nicer. They have made sure of it, creating a tranquil haven in suburban River Ridge to protect the person most precious to them.

Until the unthinkable happens, and nine-year-old Gage vanishes.

In a split second at a local carnival, the Hudsons' storybook world begins unraveling. A frantic search starts to uncover splinters in their carefully crafted facade, revealing buried secrets that cast just as much suspicion on Cal and Faith as any ill-meaning stranger, and proving that the line between love and violence can disappear as suddenly as a child on a chaotic midway.
