I have never been a fan of time travel stories, but this one, which did not take itself too seriously wasn't bad. It has a lot of Goulart's usual light humor, much of it provided by the egoistic time traveling robot. Some of Goulart's themes of a faithful relationship and health (in the form of running) also show up. The various trips into the past and associated foibles make the book a good read, if you're in the mood for something light.
