Last Tango in Ibiza took two years to write under the direction of retired journalist Willie Rocke, who suggested that the group write a novel. Each of the class took responsibility for one or more characters. Rocke had to knit the different story lines together. "There were times when I thought it would be bigger than the Yellow Pages. Juggling six different manuscripts was a challenge," he said.
Getting it published was equally difficult as it was rejected by a number of Irish publishers. Rocke reckoned the group had a book that would sell and they each put up e570 (pound;366) for an initial DIY print run of 1,000 copies. Dublin's Lord Mayor launched the book which is now in its fourth reprint. Rocke is now in discussions about a UK launch.
The story centres on a large cast of characters on holiday in the Balearic island. There is plenty of mystery, romance, drama and comedy. And, of course, steamy scenes.
But the women have taken a collective vow of silence about who wrote what. "We have our reputations to keep," said one.
