Synopsis: “Gryllus the talking pig is back. Well, strictly speaking, he's a human in a pig's body...it's a long story. After saving the Cosmos once before, Gryllus is a bit tired of being a hero. He wants to return to human form and live a quiet life, preferably working as Chief Pie Taster to the Gods. The only person who can change him back is the demi-goddess Circe - but Circe, along with all the other Olympians, is nowhere to be found. It looks like the Cosmos is in grave danger once again, and a mysterious prophecy seems to suggest that Gryllus might be the pig to sort things out. So, along with Sibyl the ex-priestess, the singing head of Orpheus, and an immortal grasshopper, Gryllus travels to the Underworld and back, and is surprised to discover just who is trying to destroy the Cosmos.” (publisher's synopsis)
