Mercer Mann, a popular writer from Camino Island, is back on the beach, marrying her boyfriend, Thomas, in a seaside ceremony. Bruce Cable, infamous owner of Bay Books, performs the wedding. Afterward, Bruce tells Mercer that he has stumbled upon an incredible story. Mercer desperately needs an idea for her next novel, and Bruce now has one.

The true story is about Dark Isle, a sliver of a barrier island not far off the North Florida coast. It was settled by freed slaves three hundred years ago, and their descendants lived there until 1955, when the last one was forced to leave. That last descendant is Lovely Jackson, elderly now, who loves her birthplace and its remarkable history. But now Tidal Breeze, a huge, ruthless corporate developer, wants to build a resort and casino on the island, which Lovely knows, deep down, is rightfully hers.

Mercer befriends Lovely, and they plunge into an enormous fight over who owns Dark Isle, taking on Tidal Breeze Corporation, its lawyers, lobbyists, and powerful Florida politicians. But Lovely knows something about the island that could seriously cloud the dollar signs in the developer’s eyes: the island is cursed. It has remained uninhabited for nearly a century for some very real and very troubling reasons. The deep secrets of the past are about to collide with the enormous ambitions of the present, and the fate of Dark Isle—and Camino Island, too—hangs in the balance.

“Once again, Lawhon works storytelling magic with a real-life heroine.” —People Magazine

Maine, 1789: When the Kennebec River freezes, entombing a man in the ice, Martha Ballard is summoned to examine the body and determine cause of death. As a midwife and healer, she is privy to much of what goes on behind closed doors in Hallowell. Her diary is a record of every birth and death, crime and debacle that unfolds in the close-knit community. Months earlier, Martha documented the details of an alleged rape committed by two of the town’s most respected gentlemen—one of whom has now been found dead in the ice. But when a local physician undermines her conclusion, declaring the death to be an accident, Martha is forced to investigate the shocking murder on her own.

Over the course of one winter, as the trial nears, and whispers and prejudices mount, Martha doggedly pursues the truth. Her diary soon lands at the center of the scandal, implicating those she loves, and compelling Martha to decide where her own loyalties lie.

Clever, layered, and subversive, Ariel Lawhon’s newest offering introduces an unsung heroine who refused to accept anything less than justice at a time when women were considered best seen and not heard. The Frozen River is a thrilling, tense, and tender story about a remarkable woman who left an unparalleled legacy yet remains nearly forgotten to this day.
