My hat is tipped to you, @riley.sager
I don’t know how you continue to do it but each book gets better and better. This one kept me on my toes until the very end. I didn’t figure out who the killer was or what had actually happened with Claudia until it was revealed. By far, this was my FAVORITE book by Riley Sager to date. Read it, audiobook it, you won’t regret it.
