'I thought I knew quite a bit about earthworms – until I picked up this charming little book' Nick Baker 'Many wonderful wormy tales unearthed by Coulthard' BBC Countryfile Magazine 'A gem of a book' Country Smallholding Without these little engineers of the earth, the world's soils would be barren, and our gardens and fields wouldn't be able to grow the food we need to survive. Worms recycle decaying plants, putting nutrients back into the soil; they provide a food source for wildlife; and their constant burrowing helps heavy rain soak away.

From the often Caldecott-buzzed Deborah Freedman, a sweet and funny story about finding your place in the world. Carl is an earthworm. He spends his days happily tunneling in the soil until a field mouse asks him a simple question that stops him short: "Why?" Carl's quest takes him on an adventure to meet all the animals of the forest, each of whom seems to know exactly what they were put on this earth to do, unlike the curious Carl. But it's not until the world around him has changed that Carl begins to realize everyone, no matter how small, makes a big difference just by being themselves.
