Ever forgotten to bring something to entertain yourself on the train? Or tried to be subtle while reading over someone's shoulder? Well, the Guerrilla Book Swap Inc is leaving you a recommendation, some entertainment, on a train, bus or tram near you.
Go ahead, take it with you and read it! Then, when you're done, leave it on another train, bus or tram for the next reader. Even better, check out the book's blog post - all the book swap books have one! - and tell fellow Guerrillas what you thought and where the book is now.
