I really enjoyed this book! I just couldn't get enough of it, I needed to know what happened. I was suspicious immediately of Isabelle but the story started to lean into the sleepwalking angle a little too much so I immediately shifted my suspicion to the husband. Already having a wife who died makes you wonder if maybe that was under suspicious circumstances.
Just when you think you have this one figured out it pivots and send you chasing another angle for answers. Such good story telling, all the breadcrumbs are there but you still don't see the twists coming.
