Ruth Ware writes books that are perfect audiobook companions for driving. In this thriller, the narrator, known in her youth as Lee and in the present as Nora, is invited to the hen weekend (bachelorette party for us Yanks) of the woman who used to be her very best friend.

They have not spoken in 10 years, she is not invited to the wedding, and heaven knows why she decides to go. Old scores need to be settled by Clare the bride, or maybe by Flo, her obsessive new best friend.

I confess I guessed most of it before it was all over, but still a good yarn, and a satisfying ending.
