Just finished
Plato: a very short introduction. Nice punchy little guide. I'm a sucker for wanting to collect every book in a given series, but there are over 200 of these cute little buggers, so that won't be happening anytime soon. Still, some very interesting topics covered, and they're a good way into a subject you might otherwise not think about studying. Archaeology will be next I think.
Currently working my way through Dawkins' 1976 classic
The Selfish Gene (30th anniv edition). A beautifully explained gene's eye view of life, but still having to concentrate as I'm definitely no biologist. Having to keep reminding myself that it's a metaphor. His speculation about how life might have emerged from the primordial soup is fascinating.
Coming up next: I've just had the
Ultimate Hitchhiker's Guide posted to me from the US, a lovely leather-bound collection of Adams' five Hitchhiker novels. Unbelievably, I've reached my mid 30's and never read any of these (so I figured I'd do it in style

).
