sunflowersky - I never considered self-publishing as an option before. I always thought traditional was the only way to go until I spoke to a bestselling author (published by one of the Big 5) who said that self-publishing might work better for a new writer like me. She said her friend self-published and is doing well. Of course I know that's not always going to be the case for every writer. There are no guarantees. And there are risks. It could backfire and jeopardise my chances with traditional publishers in the future. I told her that. But she said that the publishing industry has changed so much over the last decade alone. And independent authors now have a fighting chance. But you're right about marketing and promotion. If I'm going to do self-publishing, I'd have to work really hard and have a good strategy to promote and market my book.
In the end, it's a matter of preference, as traditional and self-publishing are both legitimate pathways to getting published. Each with their own pros and cons.
Sarah Ahlers - Yes, I've nudged them several times. I'm giving myself a deadline before I finalise my decision about self-publishing.
Curious Author - This is my second novel. The first one is sitting in my drawer, also unpublished. I must admit I did not know what I was doing when I queried the first one. So the second time around, I made sure I did it right. I researched. I took creative writing courses before starting on the second novel. When I finished writing it, I had beta readers read and critique it. Then it went through several redrafts after that. I made sure it was polished before I began submitting. Even the query letter, synopsis, and first few chapters, I had a professional editor assess those to make sure I ticked all the boxes.
TerryRodgers - You have a point. I plan to start a mystery/crime fiction series. I just don't know how quickly I could write them.
Ms Bobbie A - Sorry, no, those 15 are queries only. I'm waiting for them to reply. But I do have 2 agents and 2 publishers considering my full manuscript.
