I made a start on Hitchikers Guide to the Galaxy by Douglas Adams. But that's not really suited for short reads in public transport, so I've been looking for something else. I'll save the Guide for a later date. I started on Anatoli Rybako's Deti Arbata, but that too wasn't quite what I was looking for. Another one for the long list of stuff I still want to read. So I did another round through the house and stumbled upon Stephen King's The Dead Zone. For reasons unknown to me, King is perfect for public transport.
