That’s right – the 1st edition hardback is now sold out. If you desperately want a hardback, there are just a few copies left at amazon in the UK.
Don’t worry, though – the 2nd edition is almost ready to go! It’s at the printers right now. More details very soon.
In the interval, the 1st edition paperback is still on sale from amazon US, or better still from Createspace where it’s cheaper (see the previous post).
