IMHO, Mills and Boon novel these days are not what they were in the days of Charlotte Lamb, the old-style Carole Mortimer, the 90's Lynne Graham (I'm talking mainly about her newer books that are so not up to par). This one may well be the nail in the coffin for me where they're concerned.
In the resume, you get the words French, passion, magnate, but I think they might have been applied to this novel in error. The passion - if you use the term very loosely, was lukewarm, the guy was a chateau-and-vineyard-owner, which are two-a-Euro in France, and yes, he made a living from it, but was he a magnate? No!
It was slow and boring, and seemed to have a mother who was a bully and abusive to her daughter - even now, 7 years after last seeing her, she was still unpleasant and ungrateful - with romance taking a back-seat in the tale.
The other reviewer has done a great summary of the tale and its faults, so I won't say more, other than that I couldn't bring myself to waste my time and finish this. I was expecting young lovers who had been separated against their will to be reunited, but this tale was pretty much about everything but - and passionless on top.
Not a great intro to this author, and I certainly won't be reading the next, linked book, which from the sounds of it is likely to feature the female lead's brother. No thank you.
