I've just released four of my backlist titles as ebooks for the Kindle, with other platforms to follow when I can get around to putting the work in.
Formatting for a professional-looking result isn't the doddle that some would have you believe; up-converting a Word file with Amazon's own online tool gives a result that I personally wouldn't pay money for. These titles were put together by Paul Drummond, who offers a complete ebook design service from his website.
The books are Chimera (the genetic thriller that spawned the ITV series, US Kindle link here), creepy police procedural Down River (US link here), contemporary on-the-run fantasy Oktober (another ITV adaptation, with Stephen Tompkinson, US Kindle link here), and modern noir suspenser The Painted Bride (US here).
In the near future I'll be adding my Scandinavian supernatural horror tale Follower along with Out of his Mind, the short story collection that picked up the British Fantasy Award.
Amazon has (have?) kindly linked the new titles to old customer reviews. Unfortunately, at the time of writing this consists of three people who didn't care for the books and took the time to say so. While respecting their opinions (ya kinda hafta or you don't look too good) I'm crossing my fingers that others will soon chip in and provide some balance without me having to go the Orlando Figes route.
On the subject of embarrassing sock-puppetry, when researching the life of Daniel Defoe to flesh out Robinson Crusoe's backstory I found that one Defoe biographer had rubbished the most prominent book on the subject while writing his own a glowing five-star review. Unfortunately he must have misunderstood the process, and his real name appears on both entries.
