To be honest, if it wasn't billed as a different take on Pride & Prejudice, I probably wouldn't pick it up. So this book will always be a little coloured by that. 
 It started off pretty slow, and I wasn't a huge fan of the voice of the protagonist. Her point of view mainly seemed to be a voice of shock value for P&P fans (i.e. the characters in P&P aren't lily white, they have bodily functions like the rest of us). But by the middle of the book, I had was engrossed in Sarah's story. I was totally surprised by the "twist" in the book and that's probably when the novel became a page-turner for me. 
 I also noticed how Jo Baker took some of the characters who were objects of mockery in Pride & Prejudice and made them distinctly sympathetic in her novel. Except Wickham; he's just a villain. 
 (view spoiler)[I'm cool with the ending, Elizabeth doesn't come off so wonderful in this book, but by the end I had just accepted that this was a book that only peripherally touched on the main Pride & Prejudice characters, so I was more interested in Sarah's happy ending. The interlude in the guerrilla war in Spain was a bit weird though. I would've rather read more about Hill and what she went through. (hide spoiler)]
