"Two couples. One twisted game of love and sex. A dark domestic thriller about the dangerous secrets that come to light when a wild fantasy turns sinister... When young couple Elena and Adam are offered the chance to housesit in their dream neighborhood for a few months, they jump at the opportunity. The leafy South London enclave is a world away from everything they know, complete with grand homes with lush gardens and quaint local coffee shops. Soon, Elena crosses paths with the beautiful and enigmatic artist Sophia and her filmmaker husband Finn, and she and Adam are pulled into their orbit. Sophia is everything Elena isn't: glamorous, alluring, successful, and Finn exudes a mysterious pull on Elena that she can't seem to shake. Elena's infatuation with Finn grows stronger by the day, and when Sophia proposes a thrilling game to her new friend--to swap partners in secret--Elena quickly agrees. It's not long before Elena experiences a sexual awakening that blossoms into an illicit love affair, but Sophia's plans are far more dangerous than Elena could ever have imagined..."-- Provided by publisher.
