I don't get on with Neil Gaiman. I've tried American Gods and Neverwhere, and read through Coraline on a plane journey recently. He is dull. Although I think I might actually quite enjoy the Sandman comics. But yeah.
Other than that, Bad Science by Ben Goldacre is an enjoyable, informative read, definitely worth lending out to other people. I like Malcolm Gladwell's books too, 'Blink' and 'The Tipping Point'. Both are basically interesting bits of psychology cobbled together into some sort of unifying theme, and both should definitely be taken with a large pinch of salt.
