From the #1 New York Times bestselling author of A Monster Calls comes a richly illustrated and lyrical tale, one that asks harrowing questions about power, loyalty, obsession, and the monsters we make of others. With harpoons strapped to their backs, the proud whales of Bathsheba's pod live for the hunt, fighting in the ongoing war against the world of men. When they attack a ship bobbing on the surface of the Abyss, they expect to find easy prey. Instead, they find the trail of a myth, a monster, perhaps the devil himself.
