" This was a fantastic ending book! Again, less humor than the other books, and, really, very serious or dark at some points. The characters- every one of them, save Kronos, seem easy to sympathize with. I love how Rick Riordan can fit so many in-depth characters into the series and it still comes out so smoothly. And sometimes the twists seem never-ending. Of course, nothing wrong with that. Great read, a shame I had to finish so quickly. "
