Sophie is a twit. One of the biggest twits I've read recently. Just no. So much emphasis on the sex? Taking everything Winston says at face value? Zero questioning of anyone around her other than Smedley? Instalove at the end? SO MUCH FAINTING?
And the Americanisations (math instead of maths, pants instead of trousers). I read The Bookman's Tale on a whim and it was a light novel good for filling a couple of afternoons. I expected the same of First Impressions and I was very disappointed. The whole time I had a vague impression that something was off about Sophie. She puts way too much trust in all of these male characters (who are basically strangers to her). She just didn't read like a real woman to me. I was skimming all the Jane Austen bits at the end. Did they add anything to the story? I just wanted it to be over. Solve the mystery. Get out of there. End my misery already.
If you like this type of story, The Bookman's Tale was better. Or just skip Lovett altogether and read Possession by AS Byatt.
