This really feels like a reference index, like a dictionary, and probably would be better suited for print. Even so, it’s fun for what it is. It’s certainly one that anyone writing maritime adventures should have on hand. It’s not just sea monsters in here. All manner of customs and superstitions are listed here from crossing the equator ceremonies to beliefs of animals aboard ship to figureheads representing the soul and honor of a ship. There’s quite a bit of history here that I didn’t expect. You get the obligatory ocean gods, sea serpents, and mermaids here too, just on account. I can’t in good conscience declare this the best book on the subject I’ve read, but it’s fairly comprehensive in its variety.
