Harriet and Wyn are the perfect couple - they go together like bread and butter, gin and tonic, Blake Lively and Ryan Reynolds. Every year for the past decade, they have left behind their lives to drink far too much wine and soak up the sea air with their favourite people in the world. Except this year, they are lying through their teeth. Harriet and Wyn broke up six months ago. And they still haven't told anyone.
This is the last time they'll all be together here. The cottage is for sale, and since they can't bear to break their best friends' hearts, they'll fake it for one more week. But how can you pretend to be in love - and get away with it - in front of the people who know you best?
