I had an unusual experience a couple of days ago, when I was interviewed over the phone by Paula Berinstein of the The Writing Show (http://www.writingshow.com/) which posts podcasts online. The subject of the interview was my novel Scales, and the questions made me think harder about my approach to writing the story than I actually had when writing it!
The plot concerns a present-day Englishman - Cade - who wakes up months after being almost killed in an explosion and fire, and finds that he is no longer entirely human - he is not only covered in reptilian scales, but also has acquired some non-human abilities. The inspiration for this came from a dream I had in which such scales were growing over my skin. I wanted to explore the implications of this, so I used the first person point of view, and a linear chronology: the story is told as it happens, and the reader knows exactly as much as Cade at any given moment. This does place certain limitations on the story-telling, as every scene features Cade and we only know his viewpoint; we can't find out what's happening elsewhere, unless Cade learns about it from someone else or from a news item. However, I think it provides more immediacy and tension than a more conventional third-person narrative, and is better suited to this kind of story.
The first part of the book developed organically - I basically started writing to see where it would lead. This took me so far then left me stuck, so I put it to one side for almost a year until the outline for the rest of the story came to me (in one of those valuable sessions when lying half-asleep in bed one lazy morning).
I regard this as a rather traditional kind of novel, in various ways. There is nothing clever in the construction or techniques used, it's just a straightforward story. I don't claim any particular originality for the plot elements, which come from standard SF conventions; psi powers, parallel worlds, alien civilisations and threats to humanity (partly self-generated, partly from outside). Its length of 220 pages is on the short side by today's standards (although typical of the 1950s/60s fiction I grew up with), but it does mean that it is fast-paced. The phrase "I couldn't put it down" has been used by Paula and other readers, which is gratifying.
