The Light Between Oceans

No way on earth I would have bought this on the basis of the synopsis, but I loved the cover and it's against the law to leave a charity shop without buying at least one book. This is a story about choices, lies and consequences. The lie here is a pretty big one, the choice a bad one, the consequences are pretty dire for everyone, the ending heart-warming. I would group this together with something like Fried Green Tomatoes or The Persian Pickle Club.
