I borrowed this book from the library because it was short and has a picture of a dinosaur on the cover. It is, in fact, short, and has multiple dinosaurs in it.

I certainly have some problems with it, like its Eurocentric view of history or its tiresome equivocation of Stalin and Hitler; but its subject matter is treated so lightly that I can't be particularly upset. It is, at the end of the day, a relatively harmless & mostly enjoyable comedy overlaid on an interesting time travel premise.
