South of Aden

A skeleton in a wrecked longboat, a chart marked DO NOT LAND AFTER DARK, and ninety days to redeem a ruined career: Captain John Moresby has every reason to sail past the unmapped island in the southern Red Sea. He does not. What waits there is poisoned water, a hidden monastery, a mutinous cartographer, and a volcano preparing to tear itself apart. Redemption lies eight miles inland — and the island is dying beneath his feet.
