Lara Parker's interview in Retrofan #17 is currently on sale at Barnes and Noble and other outlets.
It's a fairly long interview, conducted by Rod Labbe, who used to post here back in the day. Her time on the series is glossed over for the most part. While the story of how Lara got on the show, her characterization of Angelique is certainly well known to most, if not all, hard-core DS fans, I don't know how interested new or casual readers are going to be that interested in her writing career but that's what a lot of the interview is about. She states that she intentionally chose to downplay the horror aspect of DS in her books because she regarded it as "a mysterious, supernatural romance." As long as she doesn't go too far from the established canon, the arrangement with the Dan Curtis estate allows her to create new characters and new locations. But she would "never" do anything to damage the show's reputation.
She said that Angelique's Descent was the most successful of her books in terms of sales. But The Salem Branch, which she feels is her best work, sold the least.
The topic of the Burton movie is addressed. She and the others were eager to do the film but ultimately disappointed that they weren't used more. This may well have something to do with Jonathan's health at the time. She says that he was having difficulty standing and there's probably some truth to that. KLS seems to be holding him up at the door. Still, it would have been nice if they had a little more to do. Maybe even some dialog.
She's less than complimentary about the movie itself. Lara felt that the film spent too much time on Barnabas being a fish out of water and not enough time on other things. She cites the lack of a connecting story, instead of a "series of elaborate set pieces."
She seems to have mellowed considerably on Darren McGavin. While she does state that he was less than amiable, she seems more understanding about the pressure of being the lead actor on a show that was not doing well.
To summarize, it's a decent interview. There are some excellent articles in the issue on Mad Monster Party, The Haunting and George of the Jungle. Retrofan costs $9.95, which I guess is the norm for genre magazines these days.
