Eleven-year-old Demon had never met his father, the god Pan, until the day he was whisked away to the stables of Olympus and charged with looking after all of the mythical creatures there, a task which is complicated by the tempestuous gods and goddesses and Heracles, who keeps killing the immortal beasts.

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.

"Demon has always counted on his magical medicine box to help him cure the sick beasts on Mount Olympus. But Chiron, his new healing master, insists Demon learn to find the cures on his own. Demon's new skills are soon put to the test when he must save an ailing phoenix--or face the wrath of its fiery guards!"--
