The Long Earth

Bit of a disappointment, really. A bunch of puns spread through it was about the only indication Pratchett was in the room. That, and the thing where the 'stepper' that moves people between different dimensions is powered by a potato. But the scooting between alternate dimensions seemed like a travelogue of 'Tuesday, Must be Belgium'. It finished on an interesting note, but was it interesting enough to send me to the next book in the series? Not so far.
