Hercufleas

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. Many have failed. What Greta needs is a hero whose courage and self-belief are greater than himself. She needs Hercufleas. The only problem: he is a flea, no bigger than a raisin. But the smallest person might just have the biggest effect .
