Really nice mix between a toolbox and a setting - the book is packed with very flavourful and detailed tables and procedures to make an island hopping game in a particular type of flooded world, creating seas with their own currents, islands, factions, Leviathans, and Tyrants. If you've read other books and zines by Lazy Litch you'll recognise the weird/dark fantasy atmosphere, but this is more extensive and suitable for a whole campaign, though I think you could also use it for areas of an existing world if they were sufficiently remote.

This is a fantastic piece of work - really imaginative and evocative, with a clear sense of what it's getting at running throughout, which sparks off all sorts of ideas just from reading it. You could use it as is, or steal parts to use elsewhere, or read it as inspiration. Very much recommended for anyone running a TTRPG.
