Percy has more adventures with Thalia (and Zoe, a new friend, too) as they try to save the Hunting goddess, Artemis and to try to save Annabeth. Atlas is in this volume as are many Gods and Goddesses from Greek Mythology and their friend, Luke comes to play in this volume too.) I enjoy the Percy Jackson books. Percy comes out of some amazing situations usually with the help of others. It was a fun read. I am excited to read the next two volumes.
