From the back of the bock (user translated):
Eastern China was a country overflowing with fish and rice, and it fed millions of people. The last 50 years have made this an inaccessible wilderness of swamps, jungles and deserts created by the foolishness of humanity.
This book contains an adventure for Mutant 2089, set in the most dangerous wilderness of Neoasia - the rainbow forest.
The deeper into the forest one gets, the more horrible the threats.
