Glamorous, divorced Sabrina and her quiet homemaker sister Stephanie never dreamed that their light-hearted game of switching places for a week would end in passion and tragedy. But Sabrina fell in love with her sister's husband, cherishing their children as her own -- and Stephanie, in the midst of an affair with a powerful London socialite, was killed in an explosion on his yacht. Torn by loss and remorse, but deeply a part of her new family, Sabrina made the decision to assume her twin's role forever. When A Tangled Web opens a year later, only one person knows Sabrina's true identity -- her husband, Garth. Deeply in love, he has forgiven her for her deception. Then a friend swears to have seen Stephanie in Europe. Sabrina feels the past and present collide, threatening to shatter her new happiness. Is her sister really dead? Or is the deception even deeper, darker, and more complicated than she ever imagined? - from Amzon
