 This book is my favorite in the series so far! It was non-stop action from start to finish, and all of it was great. I devoured this book so fast! The series is really coming together, and I am sad that there is only one book left. 
 I really like how you find out the prophecy for each of the quests early on in the story, but it never ruins too much for you. Most of the time there are enough twists/new developments that the prophesy ends up not being what you first imagined. Rick Riordan did a great job of planning everything out, and he has put together such a great and complete, detailed series. 
 The idea of the labyrinth spreading across the entire United States is awesome! I love the detail that went into it. I also found the Sphinx(which is just one of the crazy creatures found in the maze) to be hilarious! I loved that instead of her customary riddles, she has been reduced to asking fact based questions and then the answers get fed into a scan-tron machine! And when Percy and company leave her, she is moaning about having to grade the tests by hand now. Too funny! 
 I loved how this series, is part mythology, part adventure, and part mystery almost. I love seeing the characters piece together the clues and figure out what they have to do next; where they have to go, or how they have to defeat a certain monster. It is a very engaging read! 
 Annabeth's jealousy was not too endearing for me, though. I felt bad that Percy had to put up with her standoffish-ness. I was so frustrated with her at the end, with the way she ended things with Percy. 
 Rachel was interesting, I still want Annabeth but Rachel seems so nice. I don't want her to get hurt either, however; she seems like a smart girl so I'm sure she is not oblivious to the situation between Percy and Annabeth. 
 I am loving how everything is coming together and the last book seems like it will be one huge, epic battle! I cannot wait to read it!
