This is a totally fabulous book! I like it better than some of the other recent books by Riordan. In this book, Apollo has been cast down from Olympus by his father, Zeus, and is now a mortal. He lands in a trash heap and is rescued by a 12 year old demigod named Meg, who helps him get to camp Half-Blood where he must rely on Percy Jackson and the other campers to help him. He realizes that he will have to go through trials in order to regain his godly status. His character is funny, narcissistic and he soon realizes that the mortal human life is not fun at all. Can he save the oracles, his children, and the world from a previously unknown threat? Only time will tell. I look forward to reading the other books in this series!
