Greta is a girl on a mission: to venture to Avalon and bring back a hero who can save her home from destruction by the monstrous giant Yuk. Many heroes have tried before now. What Greta needs is a hero whose courage and self-belief are greater than himself. She needs Hercufleas. But the smallest person might just have the biggest effect . . .

An inventive tale filled with adventure, humour and lots of fleas, from the author of "The Snow Merchant" and "Lilliput". Hercufleas is a flea, no bigger than a raisin. But the smallest person might just have the biggest effect... Ages: 7+.
