I love this concept. From the site:

“Just get yourself to a real-life or virtual book store… and, well, buy a friend a book! But here’s the fun part: you can’t buy your friend a book because it’s their birthday or they just graduated or got engaged or had a baby or anything else. You have to give them a book for no good reason. In fact, this present out of the blue from you should shock the pants off of whomever you decide to give it to. And it’ll make them happy. And that’s the point: promote reading, promote friendships.”

The next Buy a Friend a Book week starts this Monday!
