I'm now reading Lisa Jackson's After She's Gone, about a woman looking for her little sister; they're both actresses (and daughters to a famous actress), the younger sister's really outshined the older one (causing feelings of resentment), and now the younger one's gone missing - after an "accident" on set wherein the younger actress's stand-in got shot and almost killed when someone snuck a real bullet into the gun used to shoot her character. (Yeah, I know, real-life shades of the "Rust" situation with Alec Baldwin, but this was published back in 2016.) So naturally, the older sister's on the suspect list, and she's out to try to find her missing sister and what happened to her. According to the blurb on the back, there will be other people dying and it looking like she did it, so she'll have her work cut out for her.
