TDD by example

I just managed to publish my first book on Amazon, TDD by example - here's the Kindle version. It's $4.99 if you're in the US or Canada; unfortunately, outside of those markets Amazon pretty much sets the price to whatever they want (and no, I don't get more money if you pay more for it). The print version is available from Createspace for $14.99. The book is also freely available for download as a pdf, licensed under CC BY-SA 3.0.

If you enjoyed it, I would very much appreciate if you could leave a review on the Amazon page.
