Yesterday while searching for something else in my mancave where I cling to my guns and my religion, I found my copy of FATE OF WORLDS ,by Niven and Learner. I had bought it hardcover years ago. A quick perusal revealed that it was unfamiliar. Reading the first chapter confirmed that I had not read it.
I surmise that I bought it, brought it home, set it somewhere then got busy doing other things.
So far it is a good read
