If you like Riordan's other books and were a fan of the Percy Jackson series, this book is for you. This series is based of off the Percy Jackson series, so it includes some of the same characters and mythology. But there are also a lot of new characters and story lines to keep it interesting. It has the same Greek myth gone modern feel and will definitely leave you wanting the next book! I would recommend reading the first book, The Lost Hero, before reading this one.
