We can't really remember the last Christmas because this time last year we were very busy writing our book Numericon: A journey through the hidden lives of numbers. The book is a trip through the world of maths via the familiar stepping stones of numbers. If you like what you read on Plus then maybe you would also like Numericon — and thanks to the good people at Quercus, it does look very pretty too!

To get a taste of the kind of stories that are in the book, have a look at these Plus articles:

• The art of guessing
• Watch your units!
• Constant worries
• Too big to write but not too big for Graham
