Now in paperback, the second book in this environmental epic fantasy duology explores a world where ships kept afloat by magical hearthfires sail an endless grass sea.

After setting fire to the Forever Sea and leaving the surface world behind, Kindred Greyreach dives below to find a Seafloor populated by roving bands of scavengers. Among them, Kindred discovers a familiar face working to save the Sea from the continued spread of the Greys and the ravages of the world above. But when Kindred finds herself at odds with a faction below the Sea, she and her friends will have to use every power available to them—including their link to the surface world—to forestall disaster.

Meanwhile, above, a boy named Flitch, son of the Baron of the Borders, finds himself caught in a dangerous political crisis as survivors from Arcadia and the Once-City arrive on the Mainland. As monsters from the depths of the Sea begin to surface near the Mainland’s shores, Flitch must also navigate a crisis closer to home. As Flitch, his family, and their allies search for solutions, the truth they seek may lay hidden in old stories and long-held family secrets.

Above and below, Flitch and Kindred must work together to save themselves, their loved ones, and the Forever Sea itself.

Adventure and innovation abound in this remarkable environmental fantasy duology that explores humanity's relationship to nature against a backdrop of unique fauna and flora and nautical exploration.
