I've never read any of her work other than the Dark Passions duology, but that was more than enough for me. To me, it was some of the worst TrekLit that I've ever read. When I look at some of the other non-Trek novels that she's written, I have to ask myself, who the heck thought she might be a good fit for TrekLit?!
Just my opinion. Your mileage may vary.
