Do the friendships you make on holiday have anything to do with real life? It might be sensible to hope that they don’t.

Real life, home life, family life, are all safely left behind. But not this time.

Funerals are strange things. Kitty hadn't really wanted to go to this one - a old school friend she hadn't seen for years - and she hadn't bargained for the way it made her think of the past. In particular, it made her think of the baby she had given birth to when she was eighteen, the baby her parents had insisted she give away for adoption. She'd called her Madeleine, and she remembered her every day, what she was like, if she was happy.

Sara, teaching art at a local college, finds that she has plenty of male company – other people’s husbands, ones she tells Conrad all about, who are just good friends to her.

Viola hasn't had much luck with men. Her first husband, Marco, companion of her youth and father of her only child, left her when he realised he was gay. Her second, Rhys, ended his high-octane, fame-filled life by driving his Porsche into a wall. No wonder her family always believes she needs looking after, and her friends think she really shouldn't be allowed out on her own...Which is why, at the age of thirty-five, she finds herself shamefully back at home, living with Mum.

Every July, the lucky owners of Cornish holiday homes set off for their annual break. Loading their estate cars with dogs, cats, casefuls of wine, difficult adolescents and rebellious toddlers, they close up their desirable semis in smartish London suburbs - having turned off the Aga and turned on the burglar alarm - and look forward to a carefree, restful, somehow more fulfilling summer.Clare is, this year, more than usually ready for her holiday.
