I have to admit this was not one of my favorite books - however, I did want to finish it to know what happens... so it wasn't THAT bad :) It is probably more a 3.5 It is a about myth, it is about science - lots of science - the kind that makes your head go ... "what???" ... but that is also the kind of science that I do enjoy reading... it is about different realities. What is reality - is it yours or mine that is true? In the book, a machine, named Nellie, has been developed that can project a researcher into one of an infinite number of possible futures of Earth, however, there is only a 50% chance of bringing that person back again. It begins with "a researcher" - we do not know which researcher - found floating in one of the possible futures of Earth... Earth IVn to be exact :)
By 1982 I was back together with Linda after a separation of several years, together enough that we went down to Tampa/St. Pete, Florida for me to meet her paternal grandmother. It was scorching, the water was too salty and too warm to be refreshing. The only escape was the mall which, fortunately, had a used bookshop where I picked up this title.
