After a sea battle between the Olympians and the Titans, the Olympians find themselves shipwrecked on an island, and when Uranus' stars falls into the ocean, a dangerous wave of bubbles heads towards the island.

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.

"Demon's life on Mount Olympus has never been busier. Thanks to the awful heroes down on Earth, Demon has even more injured beasts to care for. And worse still, the goddess Psyche wants Demon to "borrow" Zeus's prized eagle for an urgent mission. But is her task worth the risk of offending the king of the gods?"

A heat wave induced by the rule of Hyperion compels Zeus, Poseidon, and Hades to search for answers about why the titan is overheating the world, a mystery that is complicated by their efforts to rescue Hera and outmaneuver the minions of their nemesis, Cronus.

When the god of war leaves his smelly, unhappy battle dragon with Demon, he must figure out a way to cure the beast without his magic medicine box.

Having proven himself capable of caring for the mythical creatures that dwell on Olympus, eleven-year-old Demon is summoned by the great god Hades to the Underworld to tend to Cerberus, the three-headed dog Guardian of the Underworld, which has been beaten by Demon's nemesis, Heracles.

Ten-year-old Zeus is kidnapped by the terrible Titans, merciless giants who enjoy snacking on humans, and when, in self-defense, he pulls a magical thunderbolt from a stone, he begins an adventure to rescue his fellow Olympians from the evil Cronus.
