When Percy Jackson receives an urgent distress call from his friend Grover, he immediately prepares for battle. He knows he'll need his powerful demigod allies, Annabeth and Thalia, at his side; his trusty bronze sword, Riptide; and . . . a ride from his mom. The demigods race to the rescue to find that the Titan Lord Kronos has set up his most devious trap yet and that the young heroes have just fallen prey.Riordan, Rick is the author of 'The Titan's Curse (Percy Jackson and the Olympians Series #3)', published 2008 under ISBN 9781423101482 and ISBN 1423101480.
