Lyrical and lovely middle grade chapter book about forging new and precious friendships with trees.

When Crowscare the dog runs away and leaves Cai all alone, there is nothing else for it but to follow her through the hawthorn hedge. The pair find a wild natural world on their doorstep, and Cai discovers a fabulous talent, to be able to talk to trees...

They learn that the Root-Kin are threatened by human ignorance and pollution - but what can little Cai and the wild-spirited Crowscare possibly do to save them and the Gnarly Queen?
