I really loved it! Thank you to all those on this thread who recommended it, I'm not sure I'd have found it otherwise.
Sarah was a great character, and it was a lot of fun to have the P&P crew knocking around in the background. I loved the writing style, and it had a decent twist (though I saw it coming very early on - I wonder if it was in fact meant to be guessed in advance?)
It has given me a taste for more novels of the period, so I've picked up North and South as my next book, it's been sitting unread on my shelves for quite a while...
