Another impressive story. This delves a lot deeper in mythology that before. With 100 Handed Ones, Janus and so many more. And I love how Rick Riordan shows us his version of the famed Labyrinth! 
 This book has more of a romantic undertone. Jealousy and tough choices await both Percy and Annabeth. But still all light which is perfect. We also get to know a bit more about Hera, Poseidon and Dionysus. And so many monsters!!! Wow! 
 I also appreciated the Colorado references having lived there. From the more well known Garden of the Gods to a lesser known museum (this impressed me a bit). Very eager to read the last book-in fact I have it nearby ready to go within the next few days most likely.
