Astronomicon: Icarus to 99c (that's 79p here in the UK) on Amazon has been the most successful offer I've launched to date.
As I've said before, science fiction thriller Icarus has had good reviews and no bad ones but, better than that, almost everyone who buys it seems to go on to buy all the other Astronomicon books. That's the best vote of confidence I could ask for. I should take this opportunity to again say thank you to everyone who has taken the time to review my books. It's nice to get feedback, especially the positive kind, and it helps encourage other people to give my books a try.
The most bizarre thing I've experienced with Icarus is that almost all my sales are on the other side of the Atlantic. The US and Canada account for well over 90% of the worldwide sales. Prior to starting the 99c offer, about 60-65% of my book sales were here in the UK. Why Icarus appeals so strongly to those on the North American continent is a mystery to me. If anyone over there understands why Icarus is SO much more popular over there, please let me know.
You can check out Icarus on your local Amazon website, see more reviews on Goodreads.com or find out more about the whole of the Astronomicon science fiction series on the Official website.
