How to Build a Time Machine

Other books on time travel, for instance by Brian Greene and Lisa Randall, assume that you have a pretty good background in theoretical physics and things like Riemannian manifolds. "How to build a time machine" by Paul Davies does not require this background. The book is a quick overview of whether building a time machine is possible (yes) and how you might build one (really, really hard to do).

One of the fun parts of the book, for me, was the indirect reference to physicists whom I know--John Wheeler, Steve Lamoureaux, Wojciech Zurek, and Mike Leitch. Their work was not explained and they were not mentioned, but it was fun to go 'Wait, I know who did that.'
