What I found was The Liar's Wife by Kiersten Modglin. I listened at 2.0 speed and finished the book by dinnertime. It's an easy listen, there aren't a ton of characters so it's easy to keep people straight when you listen to while you work.
A couple of things that are done in the book that I really liked. The main character Palmer has just given birth and as the book begins you aren't sure if she is dealing with normal post-pregnancy worries and attachment to her new baby or if her husband is truly up to no good. Up until a certain plot point I was not sure if she was a reliable or completely unreliable narrator. I am not going to tell you which it is, I don't want to spoil you.
At the very end of the book is a plot twist that you will either love or roll your eyes.
