Press Enter/Hawksbill Station by John Varley, Robert Silverberg (1990, Paperback)

This is like the old fashion double novels. You read one story and flip the book to read the second story. Press Enter is about a computer programing that has become self-aware. It has the ability to defend itself. This story will make you feel paranoid about your computer. The main character is a Viet Nam vet who is making his own business when he starts a relationship with the young girl next door.

Hasksill Station is about political prisoner keep in the distant past with no possiblilty of parole. There are so far in the past that there are no land animals. It is an all male prison with no guards. It is a real night mare. Many of the prisoners have only a loose grip on reality.

This is not a common book. I think less than ten can be found on eBay. It is worth a read for sure.
