The merciless Cronus and his Titan buddies are in hot pursuit of Zeus, Hera, and Poseidon, who plan to travel across the treacherous boiling sea in order to save a fellow Olympian. They have a boat, but they also have a problem: Poseidon can't swim and is terrified of the water (well, really of the creatures that lurk in its depths). The group faces danger after danger as they battle singing sirens, a fishy and ferocious Titan named Oceanus, and people-eating...

When Zeus, Hades, and Poseidon continue on a new quest in the search for the Helm of Darkness, they discover many things in the Underworld that Hades does not fear except a giant three-headed dog.

The Olympians must face the fierce giant Typhon in order to find magic seeds that will help grow the earth after the terrible drought brought upon the land by Hyperion.

After overcoming many challenges, Zeus and his fellow Olympians arrive at the temple at Delphi--only to find a giant snake guarding the entrance. Beyond the python, Pythia appears. Trapped in the temple by the python's magic and mere presence, Pythia urges the Olympians not to worry about her, for they are urgently needed on another quest. The Olympians are now out to find the Spear of Fear. A group of Amazonian women currently have it, but it really...

Zeus and the rest of the Olympians try to rescue Artemis from the clutches of a titan named Crius who has her under a sleeping spell.

But their rule is about to be put to the test by ten-year-old Zeus and his fellow Olympians. Join them as they discover their powers and try to claim their rightful place as leaders in various realms of the universe in the action-packed chapter book series!"--

Perseus and the Olympians face off against the snake-haired Medusa.

When Zeus meets a boy named Hermes who claims to know the Olympians' next quest, Zeus repays the information with winged shoes, setting off an adventure to fulfill Pythia's next quest and find a winged horse.

When Hercules vandalizes Eurythseus' temple and Eurythseus threatens war with the Olympians, the Oracle Pythia decides that Hercules must present him with a scale from the nine-headed serpent, Hydra, to make amends.

Two quests down, one to go! Then, hopefully, King Eurystheus will finally forgive Hercules and not declare war on Mount Olympus. Zeus nd Hercules have acquired the Amazon warrior queen's golden belt and the Hydra's scale. All that's left is to bring Cerberus, the three-headed guardian of the Underworld--gulp!--to King Eurystheus. Hopefully, Athena can get Hades to loan them Cerberus until the quest is completed. But when the trio arrives at the Underworld,...
