My rating: 2 of 5 stars
I had a hard time with this book. At times it wanted to be a pop culture reference to time travel, making references to Bill and Ted, H.G. Wells, Marty McFly, and The Doctor, but not enough to justify their inclusion. Other times, it wants to focus on the science, which often gets a bit heady and hard to follow. Most times, it wants to be funny, but I found most of the jokes falling flat. There are other books out there on this subject that are much better than this one.
