I have written a short e-book on the likelihood of there being extraterrestrial intelligent life and how humans have tried to find that life and make contact with it. It is based on a number of posts from my blog. The book is available to download from Amazon in Kindle format by clicking here.
The book will be free to download until the end of Thursday 13 August GMT, after which time it will be £1.99.
I have also made my earlier e-book on the Moon available on the same deal. This can be downloaded by clicking here.
