A very twisted story about it all not being what it seems.

1988
Beth is 14 when she's taken to Raven Hall to live with the Averells by her Aunt who can't take care of her. She soon feels like she becomes a part of the family. Nina (the daughter) becomes her best friend and besides a few things (like not being able to go to the village and being homeschooled), live is good.
Until Beth is asked to play a game when Nina's grandfather comes to visit.

2019
Sadie is invited to be a part of a murder mystery at Raven Hall. The guests/actors are an ecclectic bunch all invited to play. Until one guest goes missing.

There was so many twisted revelations at the end that it sort of made my head spin. I liked the characters of Beth and Sadie but not many of the others. I think it's worth reading but I liked The Au Pair a bit more
