"Thrilling…A topical and deftly satirical novel." —Anna Mundow, Wall Street Journal**

In this taut, dystopian tale, an island nation ravaged by the Change has built an enormous concrete barrier around its coastline—the Wall. Joseph Kavanagh, a new Defender, has one task: to protect his section of the Wall from the Others, the desperate souls trapped amid the rising seas outside. A blend of the most compelling issues of our time—climate change, increasing fear, widening divisions—The Wall is a suspenseful story of love, trust, and survival.
