A powerful fantasy adventure fuelled by an eerie magic written by a dramatic storyteller. Magic, mystery and adventure are tightly fused in this thrilling and original drama. It's lyrical and thought-provoking, whilst being hugely enjoyable. --Julia Eccleshare, Lovereading4kids

This fantasy adventure has a wonderfully original setting... It's humorously told at a cracking pace, exploring deeper themes of ecology, conservation and power. --The Bookseller

An action-packed adventure story set in the branches of giant trees; a meticulously imagined civilisation with its own religion and myths; political treachery and intrigue; heroism, and battles to the death. No wonder then that it is being described as an epic. --Andrea Reece, Books for Keeps
