I feel like we're getting to the realm of "is this really middle grade?" with this series, but it sort of makes sense. At the point these books were publishing, the original readers of Percy Jackson were much older. This book is intense, and it's not even the finale of the series yet! We've still got one more book to go!

Go into this book knowing there are some intense moments in the battle at the end of this book that'll probably keep you on the edge of your seat. Also, this whole series is (basically) a character study on Apollo, and I love getting to see how he's evolved throughout this entire quest. He's made friends, he cares about people, and it works so well for the overall arch of this particular series as well.

Curious to see how Riordan is going to end this series becuase I'm sure it's going to be with a bang!
