Our story begins with a challenge: The Trials of Hairy-Clees are only for the bravest and most awesome gods of all. Who among them will become the ultimate champion? The pets of Mount Olympus Pet Center are a true team: They conquer epic quests as easily as Ares the pug scarfs down Mutt Nuggets and they vanquish enemies who are pricklier than the spines on Poseidon the pufferfish. But when a chicken named Hermes shows up one day, things take a turn, and before the team knows it, the Oracle has spoken and the mysterious Trials of Hairy-Clees begin! Who will become top god? And can Zeus learn to share the limelight to fight alongside Hermes?
