This book was not my favorite in the series, but I enjoyed it still. Percy sets off on a journey to save a close friend, and he had to team up with a daughter of Zeus, and a Huntress (a maiden of Artemis). Of course, Grover came along. :) They set off across the U.S. to San Francisco to try and recover this friend, as well as a goddess who was kidnapped. Percy and friends come through by the skin of their teeth, but all do not make it through the journey. The battle of the gods and titans is nearing its climax! Will Percy become what the prophecy has described, or will he ultimately change his fate? P.S. Tyson is visiting Percy next summer!
