Sunless Sea (2015)

A steamship's fuel, supplies and rising Terror put a practical price on investigating the dark. Ports offer strange stories and bargains, but the distance home makes every interesting diversion feel less harmless. The gods and beings of the Unterzee sit beyond the captain's comfortable scale of understanding. It suits readers who want dense prose and costly curiosity, provided slow travel and the possibility of losing a captain are part of the appeal.
