Explore love — the deepest, most dangerous mystery of all — in this eerie dystopian thriller! This futuristic coming-of-age series is based on a classic dystopian premise: that of a society that seems to have solved the problem of human happiness by making every "right choice" for its citizens. Cassia has always trusted the Society to make the right choices for her: what to read, what to watch, what to believe. So when Xander's face appears on-screen at her Matching ceremony, Cassia knows with complete certainty that he is her ideal mate, until she sees another boy's face flash for an instant before the screen fades to black. Facing a monumental decision, Cassia journeys to the Outer Provinces in pursuit of Ky, the mysterious "other boy" who may be her destined love. Ky has escaped death, leaving a series of tantalizing clues in his wake. But as Cassia comes closer to the point of no return, suddenly Xander reappears, and nothing is certain any longer, least of all Cassia's heart. Anything can happen on the edge of the Society, where crosses and double-crosses make the path more twisted than ever, and rebellion threatens to change Cassia's world forever.
