I recently finished the book "Invasive Procedures".
This was a book the OSC co-authored with someone else.
It took a while for me to get into the story, but that was also the case with some of the "Homecoming" novels.
The feel of the book seemed more like a Michael Crichton thriller than OSC's usual style,
which I attribute to the co-author.
I'd be interested in hearing your take on this. Was it ever made into a movie?
P.S. I just started the novel "Nation" and it captured my interest right away ...
