Bests & Worsts Reviews from Amazon

SPOILER - Do not read further if you don't want the "twist" revealed. I cannot believe the people here who say they didn't see the "twist" coming. I got it on about page 2. The unisex names (Sal and Charlie, Alex) and the author goes through such grammatical contortions to avoid saying "her, she, him, his" throughout. For example: "Sal made dinner and then Sal called Laura." Things like that. Why not "Sal made dinner and then she called Laura." The whole book, until the last chapter, was like that. So the only reason had to be that the author wanted us to assume the stay at home parent (Sal) was the mother, and the hard-nosed working parent (Charlie) was the father. And then "surprise" us at the end with the fact that it was reversed. Not a surprise at all. Which made the book very disappointing.
