I had to go check my Kindle highlights on this one because my memory's spotty with thrillers. The main plot revolves around Adam and Amelia Wright, a married couple whose relationship is, frankly, crumbling. Adam has face blindness, which is a fascinating and central plot device—he literally can't recognize his own wife's face. They win a weekend trip to a remote chapel in Scotland, supposedly for a last-ditch effort to reconnect.
But the 'Rock Paper Scissors' part? That comes from letters Amelia writes every anniversary, never giving them to Adam. Each letter titles the year's marriage as either Rock, Paper, or Scissors, symbolizing the power dynamics between them. The weekend getaway turns sinister quickly; the place is creepy, there's a storm, and you realize both of them are hiding massive secrets. The tension isn't just about whether they'll survive the weekend, but whether their entire marriage is a carefully constructed lie.
What really hooked me was the structure—alternating between Adam's present-day perspective, Amelia's past letters, and a third, mysterious POV from someone else at the chapel. You're constantly reassessing who to trust. It's less a 'whodunit' and more a 'what-on-earth-is-the-real-story-here'. The ending made me flip back to the first few chapters immediately, which is always a sign the author played fair but brilliantly.
