Now that the immediate danger to Camp Jupiter has been averted, Percy, Jason, and friends must set out to fulfill the Prophecy of Seven. Unfortunately, there was a...misunderstanding... in the camp and the friends must also dodge the Roman soldiers who are hunting for them. Gaea is coming more fully awake and her sons are posing an even bigger threat. The gods are losing their minds as they morph between their Greek and Roman counterparts. Athena charges Annabeth with following the Mark of Athena and returning something the original Romans stole thousands of years ago. In other words, this is just another adventure for a group of demigods. I just love this series. It's got a lot of humor, a lot of heart, great characters, a little romance now that they're all older, and nonstop action--anything a reader could ask for. I listen with a huge grin on my face. Joshua Swanson's narration is absolutely perfect. I can't imagine anyone else reading these now. (Although I seem to remember that someone else did narrate The House of Hades.) My one complaint is that seven demigods is almost too many to follow in one book. Don't get me wrong--I love them all and want to know what's going on with everyone. But as far as quality time? There wasn't much of it with anyone, especially the Romans. This one is told pretty much exclusively from the Greeks' point of view. Maybe it will even out with the Romans in the next one? I can't wait to see what the next installment brings, especially since this one ended on a bit of a cliffhanger. If you enjoy Rick Riordan's books, you won't be disappointed with this one.
