When I was in Ibiza I purchased "Gideon's Corpse" paperback to read on landing and take off on the journey home, because I had to switch off my kindle then. I also read the book when I was in flight to Graz from Dusseldorf. It was exciting read and I couldn't put it down, much like when I used to not be able to put down an open packet of pringles.
The hero was in principle a physicist, but he didn't act like one. There was too much explanation for me. What ever happened to "show not tell". Still there were explosions and guns and a little bit of nuclear physics.
