Fun read. It's still a kid's book, but the characters are growing and the story is getting more serious. This one doesn't feel as repetitive as the second one did either. And this is the first one that takes place in the winter holidays instead of over summer vacation. We meet Artemis and Apollo and some other fun new characters and we get some more lore. On the other hand, the pop culture references are a little much - though I appreciate the very dated reference to Jesse McCartney (who I totally forgot about). Excited to see how things wrap up in books 4 and 5.
