Gryllus is the hero of The Pig Scrolls. Gryllus is a pig. Well, not strictly speaking a pig. He's a man who got turned into a pig. More specifically, he was one of Odysseus's crew (you remember Odysseus - big bloke, hero, all round clever clogs) and the whole crew got turned into pigs by Circe, a witch, but Gryllus never got turned back. So Gryllus is a pig who can talk which, as you can imagine, causes a bit of a stir in Ancient Greece. Anyway... two of the gods have had a bet, the world aswe know it is in danger, the only one who can save everyone is a smartypants talking pig. Oh dear...
