"Books can be mirrors for whoever holds them and people don't always like what they see."
Sometimes it shocks me that I can still be so shocked. 
I feel like I read a fair number of books and of those, many thrillers. I still very much appreciate when I don't see things coming. 
Rock Paper Scissors, Alice Feeney's newest, killed it in that regard.
Adam and Amelia Wright are spending a weekend in the snowy Scottish Highlands, with accommodations at the Blackwater Chapel won through a work raffle. The chapel has been converted to a dwelling, but many elements do not seem welcoming despite having been invited as guests. 
Adding to the tension is Adam having a neurological condition called prosopagnosia, which keeps him from recognizing faces. Literary subplots also add to the appeal here.
Chapters alternate from Adam and Amelia's accounts as well as letters documenting each wedding anniversary leading to the weekend.
I spent the majority of the book feeling at once uneasy, creeped out and unsure where things were going. All to excellent effect. 
Absolutely recommended!
