Sister to the Bride — Jilly Cooper

Suffering the double burden of a broken heart and a too-tight, too-pink bridesmaid's dress, Helen finds herself in the wedding from hell. The groom's family are constantly sneering at her, her hair is out of control, and she just can't shake off the unwanted attentions of ginger chinless wonder Tubby Langley. It's enough to make a girl give up hope entirely. But then Helen meets the devastating David Carlisle. Dare she risk her fragile heart once again?
