This Weekend Doesn’t End Well for Anyone by Catherine Mack
Eleanor is attending a writer's conference in the Bahamas, with all the usual folks, and the first thing she finds is, of course, a dead body. This Weekend Doesn't End Well for Anyone is the third in the series and has a ton of returning characters, so you might be better off to read them in order.
I find this series both entertaining and annoying. Eleanor is not the most likeable main character. Most of the attendees at the conference have a grudge against her of some kind, which actually seems reasonable. She's rather self-centered and jumps to conclusions easily. The story is told from her point of view but the schtick is that she constantly breaks the fourth wall and loves footnotes. I will say that both of those work really well in the audio version, presuming her whole personality and attitude doesn't bother you too much. The footnotes you can't even tell are footnotes, they just blend into...
