My dad once said to me, "You give a lot of books three stars." I do.
I thought the climax of the book would be... more climactic. I'm really struggling to remember anything about this book. Events from the last three keep getting mixed up in my head. That's not a great thing.
Overall, the new characters were my favorite part of the series. I really admire Riordan's commitment to writing diverse characters and response to fan criticisms of his work.
