This isn’t much of a novel, however, it’s a very interesting book. The subtitle pretty much explains it, and for someone like me who loves alternate history and is interested in nuclear war (for which I blame 60’s Civil Defense public awareness campaigns — I was a weird kid who grabbed all the bomb shelter brochures at the state fair) it’s a fascinating read. If you’re looking for characters and dramatic tension you might be disappointed.
Yes our current president figures in the book. No, that’s not comforting.
