Interesting - thanks for posting. Will grab a copy of that.
I seem to collect mathematics books. However this is still my favourite book on mathematics and only because it was written by a surgeon rather than a mathematician: http://www.goodreads.com/book/show/383087.Mathematics
Warning: Took me a couple of years to get through.
Oh and 1946 copy of Calculus for the Practical Man by J E Thompson.
This sounds like a lovely book. Can't say I'm a huge fan of the "maths for girls" angle, but anything that makes mathematics more accessible is great.

Grab the nearest popcorn and watch the gender wars unfold.
In the US, the book's title has been changed to How to Bake Pi: An Edible Exploration of the Mathematics of Mathematics
Perhaps the publisher thought that "category theory" might not work well for American audiences?
