Machines Like Me by Ian McEwan

another good one. it's not enough for the novel to cover a menage a trois between two humans and a robot, a buried crime involving rape, murder and a non-rape.  It also contains an intellectual and ethical history of the development of robotics and computers, an alternate history of the 20th century that includes the survival of Alan Turing, JFK and the defeat of Reagan in 1980, as well as an alternate conclusion to Britain's Falkland Islands gambit.

hard to put down. some of the plot machinations seems a bit facile and quickly-established, and I could do without McEwan's constant interlude marker ("and then we made love") but hard to argue with a novel that does so much in so little space.
