Prose? Good. Characters? Good. Set-up? Excellent. 
 The first half of this was really something. I was enjoying myself. Megan is presented as the "pretty girl" that has all the guys falling over her, and all her girl friends (save one - God Bless Tiffany!) slowly distancing themselves from her, because they found her threatening with her beauty. Normally, heroines like this would bother me (so Mary Sue), but I like how Megan is tormented by the idea of always being seen as the "pretty face." Ambrose or "Devlin" is the male equivalent of her, and when the Duke disguised himself as a horse-breeder, and they get in each other wicks merely by BREATHING, was certainly a thrill to watch! 
 But one thing. 
 I wasn't a fan of how he took her virginity. It was far away from romantic as you could get. And that set the tone of the rest of the story. I couldn't believe all the passion building up, culminated in such a lackluster and unappealing deflowering. He was drunk! And she wasn't even sure if he'd penetrated her with his youknow or fingers, for fucks's sake! That's how clueless she was! But she "felt" his hands around her back, so with that cognitive reasoning, she deduced it HAD to be his youknow after all! 
 Then followed a "She's preggers, let's get quickly wed" subplot, which again I wasn't feeling so much. Second half of this felt like a different type of chemistry altogether, and left me bemused. Oh well. I don't regret picking up the book.
