Title: Marble Gardens
Author: Deirdre Purcell
Plot: the story of two couples who have been friends for all of their married lives; the two women were childhood friends and the husbands run a car hire business in Dublin Airport. Eily and Brian have two children while Mike and Sophie are childless. The story opens shortly after Eily & Brian's teenage daughter, Zelda, has been diagnosed with a particularly virulent form of leukaemia. A few years previously Eily fell under the spell of a 'Guru', Jay Street, who has set up a branch of his Organisation in Ireland. Under his influence she has changed her name to Riba, because in a previous incarnation she believes she was an Egyptian Princess of that name. She has now decided that the only hope for her daughter's recovery is to bring her, against all medical advice, to Jay's Caribbean island H.Q. where she is convinced her daughter will be restored to health. The book is basically the story of Eily/Riba's obsession which persists against all reason or logic, and which she clings to in spite of the risks of losing family and friends because of her irrational belief and trust in a clever manipulator.

I'd like this book Daisy if you still have it, and I'd take the Pauline McLynn one too. I am about to list a few books so if you want to swap have a look and let me know, or else I can pay you the postage cost.
