Books like Amphitrite the Bubbly

This wasn't my favourite book in the series but I think it was a good addition to it. I loved seeing some familiar faces from earlier in the series that don't go to MOA, as well as getting more of two of my favourites; Hades and Pandora, AND the awesome new character of Delphinius, but I thought the story let this book down.Maybe I just wasn't paying enough attention, because although the whole contest thing seemed cool at first, I soon found it to be overcomplicated and very badly paced, in my opinion. The first half of the book was just boring to me because the whole mermaid thing didn't interest me for some reason and then the contest came up and suddenly I was getting tons of names and rules thrown at me. By the time the first task actually started (HALFWAY through the book!) I had pretty much lost interest in what it was about. To be honest though, this was probably more my problem than the book's, because I think I am now technically over the intended reading age and I was reading this in short bursts, so the set-up chapters felt much longer to me than they probably were.Another thing that sort of bothered me was Amphitrite as a main character. Although I later came round to the fact that she was actually quite a sweet girl, at first I just couldn't see what was likeable about her. Almost everything she did was for herself and the complications and quirks of mermaid life didn't grab me. Perhaps if the opening scene had been more exciting or eventful and had shown a little more of the mermaids' lives, I would have cared more. However, as I said, by the end I liked her a lot more and I'm looking forward to seeing her crop up in later books.I really enjoyed reading from Poseidon's POV, and thought the authors did a fantastic job of portraying his character as well as adding to it in this book. (view spoiler)[I also thought Poseidon and Amphitrite's relationship developed more slowly than most of the previous crushes in the series (excepting possible Athena and Heracles?). Seeing both sides of it really made it feel more realistic and to me it was very well done. (hide spoiler)]
