The Wife and the Widow by Christian White

When Kate's husband, John, disappears after she believed he was at a conference in London, her life is thrown into turmoil. It's obvious her marriage isn't what she thought it was when Kate discovers that John never even left Australia. Another woman, Abby, lives on an island off the coast, and worries about her husband, Ray's strange behavior and feels he is hiding something. In alternating storylines, White tells the stories of both women whose lives you know are going to intersect in this clever page turner. With two solid novels under his belt, White proves he's a writer to watch.
