From the multi-award-winning author of A Monster Calls comes a haunting tale of power and obsession that turns the story of Moby Dick upside down.

The whales of Bathsheba's pod live for the hunt. Led by the formidable Captain Alexandra, they fight a never-ending war against men. Then the whales attack a man ship, and instead of easy prey they find the trail of a myth, a monster, perhaps the devil himself... With their relentless Captain leading the chase, they embark on the final hunt, one that will forever change the worlds of whales and men.
