You did it! We figured this one out! It is a truth universally acknowledged (by me for certain) that the Bitchery pretty much knows everything, and really, it's true. Scroll down to see the solution for this HaBO - and many thanks!

This HaBO comes from Alea, who is looking for a category romance:
I’ve tried all manner of variants through Fiction DB and can’t identify it.
It’s a category romance, probably from the early 1990s. Heroine has just published her third book to some acclaim. Hero has obtained the rights to film her first novel. This was highly autobiographical–including embarrassing moments and an attempted suicide jumping into “Jumper’s Creek” or some such (which I would have sworn was the title of the book, but I’m evidently mistaken) and heroine does not want it filmed.
Hero is not dissuaded and not only does filming take place–it’s on location in her hometown. Among other things, this includes heroine’s high school best friend getting a bit part playing the mother of her film equivalent. One of the reasons I’m interested in tracking this down is to reread the little jokey details of the filming in her hometown within the book. I think there were others, such as using Heroine’s school and childhood home (where her parents still live).
Heroine makes peace with her past, including her mother’s alcoholism, in part due (of course) to Hero’s persistence and support, and ends with the requisite HEA.
It sounds like this book about a book becoming a movie could become a movie itself. I think I said that right. Do you recognize this story?

Found two it might be:
– “No Winner” by Daphne Clair
– “Edge of Illusion” by Casey Douglas
“No Winner” sounds closer

Hey–one I might actually know! That never happens. Anyway, it sounds a lot like “Magic Hour” by Leigh Anne Williams, a Harlequin American Romance from 1991.
I can’t figure out how to post a link on my phone, but it sounds like what you’re describing–director hero filming the heroine’s debut novel in her hometown, her family still being there, the involvement of her old friends and the townspeople, from what I remember.
OK, maybe I can get a link to work (fingers crossed):

@AnAu, much better guess than mine! Turns out “No Winner” is about on again, off again couple, sooo probably not it.
“Magic Hour” sounds a lot closer
Magic Hour it is! Many thanks. For whatever reason, I’ve been scratching my head over this one for ages.
Is it just me or does the dude on the cover of Magic Hour kind of look like Blake Carrington from Dynasty.
he looks a little like Blake, aka John Forsythe.
