Three tiny, ancient beings - Moss, Burnet and Cumulus, once revered as Guardians of the Wild World - wake from winter hibernation in their beloved ash tree home. When it is destroyed, they set off on an adventure to find more of their kind, a journey which takes them first into the deep countryside and then the heart of a city. Helped along the way by birds and animals, the trio search for a way to survive and thrive in a precious yet disappearing world… 

The breathtaking children’s debut from acclaimed nature writer and literary fiction novelist, Melissa Harrison, author of All Among the Barley and At Hawthorn Time.               

Inspired by 1942 classic The Little Grey Men by BB, with shades of The Borrowers. A tale of disappearing wilderness that couldn’t be more relevant in today’s environmental crisis, brought to life for children by three tiny, funny, eternal beings - the hidden folk.
