Halfway through the series and it's starting to get a bit repetitive, both the books and my reviews, I'm afraid.
Because I still really liked the mythology, which for me really is the strongest point of the series. I never particularly likes Percy or Annabeth, I mean they are nice enough but the teaming up of the smart girl and the not so smart but good boy who's going to save the world is something I've seen a bit too many times before. Therefore, neither of them really stood out. The mythology, however, did. (And I know this is not the only series using a lot of Greek mythology, but it's very cleverly done, positioning it in modern America. The only thing that could have made it better would have been to set the story in Europe).
Artemis and her Hunters were introduced in this book, and made the story for me. Also, the prophecy is getting more complicated still. I did start to get the feeling when reading this that the story follows the same structure every time (both in and between the books). While not my favourite, I still really enjoyed reading it.
I read a Dutch translation of this book.
