I wasn't sure what to expect when I started this but it is an amazing book.
It is set in the future well after the Earth has been partially devastated by a nuclear exchange. The "uninhabitable" areas are set off from the cities as reserves and these are the places where the natural world has regenerated. These areas are also inhabited by an evolved, supposedly degenerate human related species called homo lapis or in slang, Ginks. The Ginks are hunted for sport by wealthy officials and the story starts with a father, Frank Drager, taking his son, Ronald on his first hunt. As you will know from reading the blurb, the hunt goes wrong and Ron is kidnapped.
The ideas in this book are startling and original and the story stays with you for a long time afterwards. Highly recommended. ( )
