I’m very pleased to say that my new book The Cosmic Keyhole is now on sale at the online book store The Book Depository. At the moment it’s available for a discounted price of just over £15 (a discount of over 40%) and you can get free delivery to the UK and many other countries too. If you want to find out a little more about the book and what it covers there’s a blurb for it on the books page.
