John Gregory (1) (1933–1993)

A very odd book. The first half is a very interesting take on the evolution of a human species. The second half is a mediocre modern day sci fi creature story. I had to skim back through to remember that much, so it's hard to recommend it.

I believe my 2 star rating is from an interesting 3 stars for the first half and then a boring less than 2 stars for the second half.
