In a pretty little village, a walled garden grows delicious food, blooms with beautiful flowers, and guards a sad secret. Entry is forbidden to all but a solitary old gardener. Little is known about him, but peculiar rumours grow like weeds.

Daisy knows what it's like to lose a loved one, and she's going to get to the bottom of this mystery - just as soon as she's picked up the grandkids from school. Together they must seek out the powerful ruler of the garden, who lives far away - a distance measured not in miles but in bizarre lands.

Max can't believe his luck when grandma picks him and his siblings up and reveals her plan. He's craving adventure, but he's going to get much more than he bargained for, with surreal landscapes, colourful characters and delight and danger in equal measure.

The Witch in the Walled Garden is a reminder of the magical bond between grandparents and grandchildren. It leaves us with a lasting message about our actions, looking after our world, and how we all have a part to play.
