Starting this weekend, they will start to reappear at retailers other than Amazon, and in ebook formats other than Kindle. At the same time, they will go out of the Kindle Unlimited program. My thanks to anyone who read them through the Kindle Unlimited option (which pays authors by pages read), but it's time to get them back out to other retailers, which I couldn't do under the terms of the 90-day contracts I had with Amazon.
The series is now five books long, three of them with Richard Hugh (aka Triple-0 Five) inside the British agency nicknamed MI5 1/2, and two of them following him into an unplanned and unwanted retirement which proves to be rather less calm and dull than he feared it might be.
The first three books got overhauled in 2014, so if you have an earlier version, please note that this offer is for the revised editions.
