The first novel I finished and actually didn’t want to lock away in a drawer to never see the light of the day again was my thriller Escaping your past. I even felt it was good enough to be sent out to agents.
A very scary moment to actually send your writing into the world.
As it happened, it was not as good as I thought and I got very few replies (one half positive). Since then, the novel spent some months on the back burner until I felt comfortable enough to tackle it again.
On a post-it on my computer, I had a suggestion of what was wrong with the story, but I couldn’t quite figure out how to change it. Then one day the solution was there. Not in a clear re-written form (unfortunately) but as a thought that this might actually work.
I am still in the process of re-writing, it has taken a lot longer than I hoped, but slowly it is shaping into a story I like again and I have great hopes for the future.
