Over the horizon, just where the sun sets, is the island of Gillyford. On the island sits a quiet little village called Tumbledown. The people of Tumbledown are a happy folk. Everywhere you go, from the little red school-house all the way to the brightly coloured houses on the seashore, you will see people smiling, laughing and living happily together. Whenever they need someone to help them, they know just where to turn: Henrietta Hedgekin.
Henrietta is a witch, but not like the ones you will find in fairy tales. With her big bushy, curly red hair and her sparkling blue eyes, no one who did not live on Gillyford would even suspect that Henrietta was a witch. Every day is an adventure for Henrietta and her young friends, Ben and Tilly as they learn about the world and help people along the way.
