Best friend. Soulmate. 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 fiance. When her career begins to unravel, she pays a surprise trip home to London. Her boyfriend Jack is out, but another woman has been making herself at home . . . And that Other Woman is Melissa.

Amy has lost her job, her fiance 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.
