My mum and brother are moving and this was in a box of books I rescued

Synopsis
One night in 1986, an abandoned baby girl is found in a cupboard at Heathrow airport. A year earlier Martha, Clio and Jocasta had met by chance, at the start of a backpacking adventure: they travelled together briefly and then went their own ways, swearing to meet again when they return home. But it would be a long time until they met again: not until Kate, the foundling, is a teenager, and all three are leading successful lives. Martha is a single, highly paid lawyer, Clio a doctor, locked in an unhappy marriage, and Jocasta a reporter, in love with a charming commitment-phobe. Which of them is Kate's mother? Why was she desperate enough to do such a thing, and how did she survive it?

Offered as an Easter RABCK and on its way to DoraChrys.

Looking at the synopsis, I think I'll like it. We'll see...
Now I've got a big TBR pile but I'll read it sooner or later.

Thanks again!
