So the smartest girl in school decides office life is not for her, opens a vegan cupcake shop and then, the night before its big opening, goes clubbing, drinks too much, etc and sleeps in. Shop then opens two hours later than advertised for its big opening. Even if she is flirting with the 'dark side', can't believe anyone serious about their business would behave like this.
Also, the second book I've read recently where the blushing, sweet, generally well behaved heroine suddenly sounds like a porn actor during sex. Too much of a disconnect.
