Since her retirement, Mrs. Pumpkin, Dr. of Botanical Sciences, cultivates marvelous plants in her garden and cooks some yummy dishes with them. At first glance her Garden seems nothing out of the ordinary: a little squeaky gate, fruit trees and berry bushes, gardening tools, a greenhouse with exotic plants. The snails and lizards snoop among the flowers, birds and butterflies dance in the air, moles and worms tunnel underground — all the usual. And yet, there is one unfathomable creature living here. Mrs. Pumpkin is clueless where it has come from. A charming and curious, Trew needs to discover lots of things: why the leaves are falling, how old is the stone, how a bird finds its own voice, how to make friends and how to live in harmony with yourself and the world around you?
