In true Rick Riordan fashion, the action picks up right at the beginning of this book and doesn't really let up until the end. Riordan doesn't wait until the very end of the book for the final epic battle; instead, you get a bunch of battles leading up to the battle with the Big Bad. As a series structure, and for middle grade readers, it actually works really well, I think. Definitely makes you want to just keep reading instead of putting the book down, anyway.

What I appreciated specifically about this particular series is that Riordan really shows character growth with Meg and Apollo. You can see their arcs throughout the entire series, and their development and changes are well done. There are also some fantastic explorations of mental health, both in this book and in past books in the series, and the emotions someone might go through dealing with an abusive parent.

All in all, a great ending to a very entertaining series. Just in time for the new book to come out next week!
