In Clark’s cautionary climate change tale, a Florida village leader in a deluged future recalls his boyhood in the 2020s.

Clark’s novel opens in the late 21st century. The “Captain,” a village elder living on Florida’s disappearing coastline, describes his youth in the catastrophic 2020s (“the Roaring Twenties”), when climate change led the seas to nearly swallow the Sunshine State. After his sailor father went AWOL from the Navy in a George W. Bush–style resource war, the juvenile hero finds a surrogate dad in the neighborhood eccentric, a hermit called Harrison, whose DIY compound is self-designed and landscaped to survive escalating storms and floods. Harrison’s mysterious partner is a striking, dark-skinned “Amazon Warrior Princess” called Calusa, an alleged remnant of lost tribes who thrived before White invasion. The boy introduces his skeptical mom to Harrison’s “Hermitage” and its peculiar ways. The little commune lacks building permits and maintains a welcoming attitude to the area’s Haitian minority, aggravating the vile, racist bureaucracy in the local housing association. But Harrison is vindicated when only his structure withstands a killer storm (“the Big One”) that drowns much of the state. A remote federal government cannot bring relief to the general populace. Only Harrison’s minicolony shows a sustainable future using tidal irrigation, shell middens, and off-the-grid technology, like solar power. The tone here is agreeably all ages, and while many “cli-fi” novels (including YA ones) maintain a dreary pessimism, Clark’s invokes the utopian rather than dystopian. Harrison, with wry pop-culture references, outlines Western civilization’s sins (like the Industrial Revolution). With the Captain by his side as an apprentice, Harrison turns disaster into positive change via small-is-beautiful philosophies, revivals of a barter economy, and conducting maritime trading among the fresh island chains wrought from post-flood Florida. Literary allusions include The Swiss Family Robinson, though readers may remember another Harrison-like visionary/survivalist protagonist in Paul Theroux’s The Mosquito Coast (1981). That guy ended a doomed madman; in comparison, this serves a more upbeat, if still bittersweet, forecast of rough weather ahead.

Florida gets a much-needed reset via climate apocalypse in a bighearted instructional tale.
