Hi Mark, again, hoping this will come up below your post and you’ll be able to find it. I also write in first person and my novel which they have said is ‘difficult to place on the shelf’ is narrated by a male main protagonist, which apparently is also working against me in the general commercial genre. However, there it is! My current WIP is narrated by a female main protagonist but also in first person as I really enjoy that perspective. I decided I’d focus on that and try to improve. It has its difficulties, as you will have discovered, but I enjoy the challenge.
