How long did it take you to write?

When I tell people I have a new book coming out people ask me ‘how long did it take to write?’, it’s not an easy question to answer.
Second Strand How longwas born (under the working title A Different Coast) in August 2014 – just after the publication of Her Parents’ Daughter. I made notes on the plot, the timeline and the cast but I was concentrating on working on A Set of Lies (which was to be published in June 2015 to coincide with the bi-centenary of Napoleon Bonaparte’s surrender to the British) so nothing was done (other than thoughts in my head) for months.
I returned to Second Strand in October 2015 and the first draft was completed on December 4. It stood at 66,439 words. Looking back, I am amazed I kept at it as the day job (PS Direct) was very busy at that time and also we were looking to move away from the Isle of Wight to Devon but the story was in my head and had to be written down.
I began the first read-through the next day. This was completed on January 2 by which time it had grown to 85,906 words. Then we moved house and I didn’t look at Second Strand for six weeks, taking it up again on February 15 for the second run-through (draft three). This was completed on March 22 by which time it had grown again to 108,460 words. It was then printed out and handed over to husband Colin to read through for his thoughts. Other things were going on in our lives and it took him a month.
My third run-through (draft 4, incorporating Colin’s comments) began on April 22 and was completed on May 2 (113,242 words); the fourth run-through (draft 5) began the next day and was completed on May 23 (104,581 words). My Final run-through (draft 6) began immediately and was completed June 2 (100,681). It then went off to the editor and was returned on June 25. Resultant changes (after read-through 6) left word count at 99,722.
The ‘final manuscript’ then went back to Troubador for type-setting, returning on July 22. Read-through 7, checking every line, every word, took a week. Anomalies were identified and fixed, words were tweaked here and there, the odd error was corrected and now I await the final proof.
There will be one final read-through (number 8) and then Second Strand will be cast in concrete as it heads to the printers.
So. How long did it take to write?
From inception? Two years.
From serious writing began? Eleven months.
In terms of hours? Very difficult to say as there were days, sometimes weeks, with not a word being read or written, then other days when nine hours or more could be devoted to it.
And after all that, it will probably take the reader just a couple of days to read.
Still… I hope they will find the hours they spend reading Second Strand as interesting, thought provoking, involving and enjoyable as I found the many more hours spent writing it.
The next question people ask is ‘what’s it about?’ – a far more difficult question to answer.
