Nature always fights back. Even after Mankind had scorched the Earth with nuclear fire, the forests regrew. New life now flourishes where it can, strange and savage. The distant descendants of the last survivors of Armageddon now live high in the interconnected branches of the vast forest, eeking out a simple existence. The Story Tellers passed on tales of the Giants, and the Time of the Great Lights, but there is little or no understanding of what has gone before; the old world erased and forgotten. Kel, and his new friend Moss embark on a journey to discover whether there is any truth in the ancient tales - and what they discover is beyond their wildest imaginings.
