What a bonus surprise this book was. It had me laughing within the first few lines and turned out to be funny, serious and gut wrenching all at the same time. The thing that impressed me the most about this book was how real it was. It was a very honest account of committing adultery and having all three perspectives made it all the more rounded. Stimson builds this story very skilfully; it's very funny and 'light' to begin with and you can't help but be led to believe this is going to be a lightweight, scratch the surface type of beach read. However, as fantasy turns to fact so too does the book become more serious and significant in describing the devastating effects of a rather unpalatable situation with searing efficiency.
Having noted other reviewer's comments on their feelings of sympathy or dislike for the characters, I found (quite unsurprisingly) that even though Stimson shows how very vulnerable and precarious the life of a mistress can be, I had no sympathy for Sara whatsoever (lets face it, she deliberately set out to seduce someone else's husband; she's hardly likely to secure the pity vote). For Nicolas I felt only a begrudging sympathy (he did try after all, though failing spectacularly, to remain faithful), and for Mal and the children an awful lot.
It was very saucy in places but it rather needed that for you to 'get' what would have tempted a man who on paper was least likely to have an affair, into the bed (and every other available surface really!) of another woman. As a wife and mum myself, it's a pretty scary read at times and a warning that it really can happen to anyone. Read it, it was superb.
