The End. Again.

Today's a day of mixed emotions. I'm simultaneously relieved and nervous, excited and weary... because, late last night, I completed the first draft of another book. I've been working on this story (a historical thriller, set in Switzerland and America during the 40s and 50s) for almost a year now, and it's been a lot of fun to write... even if I didn't have the ending fully worked out until a few weeks ago!
So now I have a draft manuscript, littered with mistakes and notes about things I have to change. Normally, I'd take a few weeks off, then go back to it and start reworking the text. However, this time, I have a dilemma: there's another manuscript!
Some of you may know that I completed the first draft of a psychological thriller last year, a contemporary story set in London. As I said at the time, I found that book particularly difficult to write and, rather than continuing straight on into a cycle of edits and redrafts, I decided to take a break from it, and write something else. The idea was to give myself some distance, some perspective, so that I could return to it with fresh eyes...
So, now I'm faced with an unusual choice. Which book do I work on? Both stories are important to me, but I'm really not sure which one I should take forward first...
That was the thought that started nagging at me when I woke this morning. And then it occurred to me that maybe this isn't the moment to choose. Maybe I'll take a week or two away from both of them, and immerse myself in some different stories for a while. My pile of books-to-be-read is getting out of control and, after all those late nights and uncertain endings, I think I've earned some quality reading time!
