2020 The Year 400

We follow Wally and his girlfriend Rangi in New Zealand as they try to stay alive in the post apocolyptic world brought on by the earth being hit by a large meteorite.
Then we fast forward to the year 400, 1000 years into the future and find a very different world.
This novel is based in part on some of the authors adventures on his travels back in the late 1950’s up through to the present day.
