The Lees of Laughter’s End by Steven Erikson
Synopsis from GoodReads:
In the wake of their blissful sojourn in the city of Lamentable Moll, the intrepid sorcerors Bauchelain and Korbal Broach — along with their newly hired manservant, Emancipor Reese — have set out on the wide open seas aboard the sturdy Suncurl.
Alas, there’s more baggage in the hold than meets the beady eyes of Suncurl’s hapless crew, and once on the cursed sea-lane known as Laughter’s End — the Red Road in which flows the blood of an Elder God — unseemly terrors are prodded awake, to the understated dismay of all.
It is said that it is not the destination that counts, but the journey itself. Such a noble, worthy sentiment. Aye, it is the journey that counts, especially when what counts is horror, murder, mischance and mayhem. For Bauchelain, Korbal Broach and Emancipor Reese, it is of course just one more night on the high seas, on a journey without end — and that counts for a lot.
