Whether it's through an old attic, a mysterious tree house, or a speeding Delorian, the idea of traveling through time to another era makes for great storytelling. Inspired by a new television series that hooked us recently, we look at time travel as a genre: from why we love it to how different authors handle it. We offer some book, TV and movie suggestions for other fans of time travel and, of course, we also share what we're reading and what YOU've been reading lately.
