To find a buyer with deep enough pockets, Avra must ask for help from his on again, off-again ex, the pirate captain Teveri az-Haffar. They are far from happy to see him, but together, they hatch a plan: take the information to the isolated pirate republic of the Isles of Lost Souls, fence it, profit. The only things in their way? A calculating new Arasti ambassador to the Isles of Lost Souls who’s got his eyes on Avra’s every move; Brother Julian, a beautiful, mysterious new member of the crew with secrets of his own and a frankly inconvenient vow of celibacy; the fact that they’re sailing straight into sea serpent breeding season and almost certain doom.
