The third book, '21st Century Light' (and the longest story to date), is now complete. After a few last minute tweaks and a visit to my copy editor, it'll be off to the printers. The cover for it is being crafted as I type - and it looks AMAZING so far. I'll post the finished design as soon as I have it!
So far, everything's 'on track', so my fingers are crossed that this will continue. Hard to believe that, in another week or two, I'll be turning my attention to the next book in the series - 'Chemical Light'. :)
