This one was just really funny. I think it was good for what it was: a comedy about pirate adventures.
Sometimes I did find the sexual innuendos and the overt comments about sex a little too much but I learned to love Avra anyway and I'm glad he was able to find some people who also loved him for who  he is by the end.
I felt like Julian was the only one who really understood him through  the book and I liked that a lot. And I loved that he helped Captain Teveri understand him more too. I felt like they could be a really great throuple.
I will say that the ending was a little bit more ambiguous than I would like. It left a lot of things up to you to decide even big plot points. The whole book was about trying to figure out this secret formula to keep the sea serpents away from ships and

though it seems like they were close to figuring that out completely, they never actually show on the page that they do and that kind of bothers me.

It's fine to leave some things up to speculation but I feel like leaving the main plot up to interpretation shouldn't be one of them.
I think the pacing was a little off too. I remember looking at the percentage sometimes and realizing I had only made it through a little bit but so much happened or the beginning was dragging on or there was only an hour left and still so many things left to tie up. It was just odd.
Either way though, I had fun with it and I would probably recommend it to anyone who wants a good laugh and likes pirate books.
