Surprisingly, the transformation of the protagonist is pretty much the original aftermath of Ovid’s Salmacis story from Metamorphoses.

The rest of the book is just standard Bedek: a non-cis person, this time being genderfluid, getting a supernatural transformation and coming to terms with their hitherto ignored aspect of their personality. Oh, and »harem«/polyamory plot elements. Also, they are rich, which always helps

The story isn’t all that gripping, the editing could be better, but, meh, good enough.
