Need Help Deciding What to Read?

Someone recently asked me how I decide what books I want to read. Good question, I thought. The truth is, I find choosing new books (and new TV shows, movies and everything else) exceptionally difficult. As a rule, I try never to immediately follow a sci-fi with another sci-fi or a mystery with another mystery but that still leaves me spoiled for choice....As you might expect, the internet is ready and eager to try to help. Here's a whistle-stop tour of three websites that give you customised book recommendations.
