Best friend. Soul mate. Confidante. Backstabber. Amy thought she knew who Melissa was - then again, Amy also thought she was on the verge of the wedding of her dreams to her long-distance fiancé. When her career suddenly begins to unravel, Amy pays a surprise trip home to London. Her boyfriend Jack is out, but it looks like another woman has been making herself at home. And that other woman is Melissa. Amy has lost her job, her fiancé, her best friend and her home in one disastrous weekend - but instead of falling apart she's determined to get her own back. Piecing her life back together won't be half as fun as dismantling theirs, after all.
