Operation Sunshine by Jenny Colgan
Evie needs a good holiday. Not just because she's been working all hours in her job as a receptionist for two high-powered plastic surgeons - but also because every holiday she has ever been on in her life has involved sunburn, arguments and projectile vomiting - and sometimes all three at once. Why can't she have a normal holiday, like other people seem to have - some sun, sand, sea and (hopefully) sex?
So when Evie's employers invite her to attend a conference with them in the south of France, she can't believe her luck. At last, the chance to hob nob with the rich and glamorous, to party under the stars, to live the life she's dreamed about. It's certainly the holiday of a lifetime - but not quite in the way Evie imagines!
