It really is disconcerting when someone points out to you a published book that appears to have an awful lot in common with one of your works in progress.
Fortunately, when I sat down and read the thing*, the similarities do not seem so worrisome after all. I figure that a plot that opens "person is called back into service to solve the death of former professional colleague in a complex and alien political situation and has conflict between that and staying with much-loved family she has built since retiring" and a plot that opens "person in service is trying to solve some murders in a complex and alien political situation and has conflict arising from having to work with former family with whom she broke up messily and by whom she feels devastatingly betrayed" are sufficiently distinct, even if in both cases the complex and alien political situation is quite a bit like the contemporary West and the protagonist is coming from somewhere very different, so her reactions are illuminating more about her and the place she comes from than about the world she is investigating.
Also, a couple of things that were Big Twists at the end of the published work are potential issues that my protagonist grasps, worries about and engages with pretty much immediately. I'm not sure how to feel about that. It would be nice to be able to think my book is more complex; I like complex.
On its own merits, so far as I can see it independently, the published book in question struck me as neither notably good nor notably bad in any way worth remarking; it's a great relief that it wasn't a brilliant work of genius that's likely to sweep major awards and be the thing to which my WiP, if it ever got published, would be compared by every reviewer by default in the way that epic fantasy gets compared to Tolkien. The couple of things about it that strongly did not work for my personal tastes are things I was already not doing in my own book.
Has anyone else had an experience like this ?
*Metaphorically. It was short, and I have had a lot of running around to do this past few days, so I read most of it walking along or standing on public transport.
