I went into this story expecting to dislike it and stop reading halfway. The reason for it being the premise as told by the summary: when Darcy leaves after the day after the Netherfield Ball, he apologises to Elizabeth in case he raised her expectations, because he can't marry her due to the difference in their stations, not knowing the Bennets have inherited a title and dukedom.
That right there is the reason I expected to dislike the story. But it's also the reason I gave it a read anyway, since it's obviously a D/E HEA, when after those words the whole thing should be beyond repair and the D/E ship should have sunk.
In truth, I'm not sure I like how that obstacle was overcome in this story. But I can definitely say without spoiling anything it wasn't as wishy-washy as one might fear.
The D/E romance takes a backseat, however, to the Bennet family's adjustment to their new circumstances and the consequent changes wrought, which takes up a huge part of the story. I approve.
[ Lydia sighed. 'I hate growing up. It is a great deal of work.' ]
And this proves true for all characters throughout the story.
My favourite part is the gentle set down Mrs Bennet gives to Darcy, reminding him of his own words and his behaviour in Meryton, and what that means now that the shoe is on the other foot. Mrs Bennet's motive isn't revenge, but rather mercy: she knows Elizabeth would have phrased things in a way that would have destroyed Darcy.
[ 'When did you become so wise?’
‘When I stopped being afraid of the future.’ ]
That just about sums up the hows and whys of Mrs Bennet's character changes in the story, and why it's not as OOC as some readers think.
And once she's curbed her excitement, with the help of some new friends, why should Mrs Bennet have trouble fitting in the ton? As she says in-story, they're still women, and Mrs Bennet knows how to handle women. And she thoroughly enjoys that the shoe is on the other foot now: now it's the men who have to pursue her daughters because she made it known her daughters would marry for love and respect or not at all (they can afford it) and she gets to enjoy watching them be courted by all and sundry.
One side effect of all these changes in the family and their circumstances is that Jane's eyes are opened to the real world. It helps that Caroline humiliates her twice, once when Jane visits her in London before her new status is known, and once at the very ball intended to introduce the Bennets to the ton (a ball to which Caroline is of course late and thus doesn't know the mistake she's making).
As such, naturally the Jane and Bingley ship sinks, hard. But no worries, there's a deserving gentleman waiting in the wings for Jane.
Caroline learns her lesson too late, but she's willing to accept that. (And maybe this acceptance of her own fault is what makes some readers cry OOC, but to that I only have to say that likely as not they've read too many crazy!Caroline stories and lost objectivity.)
There's also naturally the obligatory "Collins fumes and blusters and insists he's Mr Bennet's heir to the dukedom too, when his line was deliberately disowned in perpetuity". In his case though, the acceptance did come too fast. One minute he's insisting he's given his due, the next he's immediately contrite without anything resembling a transition. That bothered me simply because it didn't feel remotely realistic (for a given definition of the word, naturally).
Overall, I really enjoyed reading this story. It's a light-hearted feel-good story for a rainy day.
But I cannot give it a 5 star rating. The technical quality just isn't good enough for that. The author really needs a good proofreader.
In truth, I'm rounding it up from 3.5 to 4.
