The Arrangement by Sarah Dunn

A Co-worker recommended this read to me. It is an adult title. I put it on hold at the Library a few months ago and it just came in! It is an intriguing plot. A seemingly happily married couple decide on an arrangement, an open marriage for 6 months. At the end of the 6 months they will stop the arrangement and return to their ordinary life. The question is, how can you ever return to your life before?

Amazon Summary

Lucy and Owen, ambitious, thoroughly-therapized New Yorkers, have taken the plunge, trading in their crazy life in a cramped apartment for Beekman, a bucolic Hudson Valley exurb. They've got a two hundred year-old house, an autistic son obsessed with the Titanic, and 17 chickens, at last count. It's the kind of paradise where stay-at-home moms team up to cook the school's "hot lunch," dads grill grass-fed burgers, and, as Lucy observes, "chopping kale has become a certain kind of American housewife's version of chopping wood."

When friends at a wine-soaked dinner party reveal they've made their marriage open, sensible Lucy balks. There's a part of her, though-the part that worries she's become too comfortable being invisible-that's intrigued. Why not try a short marital experiment? Six months, clear ground rules, zero questions asked. When an affair with a man in the city begins to seem more enticing than the happily-ever-after she's known for the past nine years, Lucy must decide what truly makes her happy-"real life," or the "experiment?"
