Four years after Bitterblue left off, a new land has been discovered to the east: Torla; and the closest nation to Monsea is Winterkeep. Winterkeep is a land of miracles, a democratic republic run by people who like each other, where people speak to telepathic sea creatures, adopt telepathic foxes as pets, and fly across the sky in ships attached to balloons.

But when Bitterblue’s envoys to Winterkeep drown under suspicious circumstances, she and Giddon and her half sister, Hava, set off to discover the truth–putting both Bitterblue’s life and Giddon’s heart to the test when Bitterbue is kidnapped. Giddon believes she has drowned, leaving him and Hava to solve the mystery of what’s wrong in Winterkeep.
