**Actually a 3.5-rating**
Pretty much what the summary gives us, except--well, this type of romance trope set-up used to be my catnip of choice. But then when I would do that thing that a reader does when you want ALL THE THINGS and you gorge yourself on your guilty pleasure, many of them never live up to your deepest want or desire in a genuine romance.
I see people on here being upset that Viscount Osterley [ Harris Dane ], or Osterley as Felicity is want to call him dares to have an outside paramour/mistress. Actually he seems to be widely known as Austere Osterley, eh, because he always seems to have a stick up his bum. Anyway, he is a red-blooded dude so I cut him a break for having a mistress even when he might have unrequited feelings for his ward.
Felicity is the baby sister of his best male friend. Seems an entire set of families was riddled with smallpox and many had perished, leaving Felicity in Harris's care. She would often be that annoying 3rd wheel when Harris and her brother, John, would play as boys, but she may have grown up along with Harris for quite some time. She isn't of age yet where she can live on her own --one more year--so, she has been under "ward-ship" with Harris for going on 4yrs now.
Harris is at some fancy French designer dress shop when he special orders a scandalous silvery/lacey dress for his current paramour, Mrs. Grace. Of course, while he is in the shop and about to finalize the sale...he gets spotted by people who know him so he hurriedly picks out a set of fancy embroidered gloves for Felicity. So, already, you know there will be a mix-up because Harris seemed to not even want it known he was ordering a dress for a mistress. When the dress and gloves are about to be sent out for delivery, placed in the wagon or something...an accident occurs and the address labels are not simply switched, but one is lost--the one for Mrs. Grace. Hence, why EVERYTHING Harris ordered will be arriving for only Felicity.
Even though she is a ward of Osterley, an "Aunt Bertha" has been chaperoning Felicity these last 4yrs. And it is a group of women who not only find the gloves, but also this mysterious, yet gorgeous dress. Felicity will be entering Almack's tonight, so...yeah, they plan on having her make quite an entrance. More than she bargained for.
Here is what was off-putting... Harris's scapegoating anger, what almost felt like -to me- hatred toward Felicity. He is quick to anger having seen that dress meant for his mistress being worn by his ward and...well, he did start to look at Felicity with different eyes, but he squelched that, snuffed it right out. Instead, he becomes a deplorable meanie by using displaced anger toward Felicity instead of being a better man and taking the full blame on himself.
Now, he becomes a full-on fire-breathing anger rager and he says he is going to force Felicity to leave the London Society and make her go live in the country to escape ridicule and gossip. This is why it downgrades in rating because...this whole rest of the story becomes pointless except to "force proximity" on Harris and Felicity now, so they can have a battle of wills face-to-face. Harris had a plan all along to simply drop Felicity off and abandon her to his old family estate where they both used to live.
Then a bridge, literally, washes completely away during a severe rainstorm which now imprisons Harris within Felicity's vicinity even though he wants to be very far from her. And we truly don't know exactly why he seems bipolar with her. On days where he's back to his old self, she calls him "Harris"...but when he's being all stoic, cold and mean, she'll call him "Osterley".
The time they spend here actually gives not just them a chance to restart their old bond of friendship, but also give Felicity a chance to say goodbye to old ghosts who still haunt her and haunt this old place that Harris has done some massive renovations with.
They play a silly childlike game of Hide-and-Seek merely because they battle one another on who knows this house better... Him or Her. So, yeah...they have a few moments of brushes with intimacy and almost kisses. That is until Harris makes an unforgettable confession of where his feelings for Felicity may actually lay...and he sparks her interest by claiming, "I cannot lose you, too!"
This causes Felicity to take a chance, for once, and seek Harris out on her own, since he finds running away from her preferable whenever emotions get heavy. So, yeah...she puts on that silver dress again...and sex happens. They both confess love and by morning...Felicity is alone, fearing the worst. She has been left alone to perish in solitude while Harris ran away to hide from his feelings or even worse, he had some idea she slept with him only to get him to bring her back to London.
Because this is a novella, Felicity is not going to wait for Harris to make a move, she makes her own and is on her way, back to London, to get her man. And...POOF! HEA...well, she actually learns she hightailed it to London for no reason because Harris had left a small note on his pillow that he would be back but did have to return to town. He was all prepared to inform people he was about to ask Felicity to marry him while obtaining the family heirloom ring, so, yeah...it was a complete stand-alone, but still a part of this series.
