My comments are from a reader's POV, I’m still very much learning the writing craft.
I was transfixed from the first line, which is great by the way. Loved the Neil/Caro relationship, very realistic. I was a bit confused at first by the ghost light thing but that’s probably just me and I picked it up later.
Great concept, story, writing, really well done.
I cannot believe the agent hasn’t got back to you. What about self pub? From what I read, series are the way to crack that particular nut. Wonder whether you could develop a series of books with Neil investigating various deaths? I think that would be mega popular.
So enjoyed this. Would happily read more. K.
