Part Victorian comedy of manners, part mystery novel, part time travel adventure, this is one of the oddest science fiction novels out there. If your idea of SF starts and ends with space ships shooting lasers at each other, you will be very surprised by To Say Nothing of the Dog, a time travel story inspired by Jerome K. Jerome's novel Two Men in a Boat. The books is at its best when it focuses on the point of view character's attempts to navigate upper class 19th century English society. There are some very funny moments, but the whole tone is a bit on the overly sweet side. A nice change of pace from the grim dystopias that tend to be SF's default mode.
