As others have given some outline of the story here, I will not add to it. This is an enjoyable read based around the concept of time travel and the author handles it well, giving us some insight into how over a relatively short period perceptions and opinions change, and how various inventions which we now take little notice of were once only ideas in the minds of sci-fi writers. Stafford takes back to 1947 a few items from his own time (2017) but I found it odd that when using one of these (a video camera) to prove that he was from the future, he only showed the device and said what it was, why not take a few seconds of video and replay it? On another occasion there is an apparent miracle, when Stafford apparently uses his smartphone to locate his position relative to the Roswell crash site - it would appear that 2017 smartphones can do this without the befit of satellites to provide GPS location! These minor criticisms aside I enjoyed the book immensely and can recommend it.
