When the sea turns against its champions, only the boldest dare ride its fury.

The Funnel is the gnarliest break in North America. It’s where fame whispers on the salty breeze, and surfers gamble with death to claim their glory. Only hardcore riders are welcome—posers need not apply. Here, skill, moxie, and money rule. But this season, an unnatural fog creeps over the Pacific, thick with the reek of decay, and the ocean churns with something far worse than the usual risks hiding beneath the surface.

Fallen surf legend Gerard Noll is grappling with life beyond his pro career while The Funnel Big Wave Competition, his lifeline for Liigei Too, teeters on the brink of cancellation as a series of unusual events disrupt the calm of Purgatory Beach. The blue void stirs, concealing creatures of the deep hungry for flesh, and Gerard is caught between saving lives and facing the relentless tide threatening to wash away everything he holds dear.

To survive, he must summon his lost courage and rediscover what once made him a champion. Will Gerard conquer the terror in the tide, or will Purgatory Beach earn its name?

From the author of Wolves of the Sea, Drop Off, The Breach, and Terror Lake comes a new sea monster thriller that blends relentless suspense, visceral fear, and the raw, untamed spirit of surfing.
