Can't remember what drew me to the book but it seemed to have a vaguely reminiscent of the background to 'Downton Abbey' (woman from the Northeast US with money gets engaged to a member of English aristocracy) and it has pretty good rating but...I'm not sure why I picked up this book.
Merry is a young woman with money who has jilted two men. She accepts a third man...only to realize she has the hots for his twin brother. And the twins don't like each other. But she really wants to sleep with Trent, who feels the same way. And cue shenanigans, drama, fraternal tensions, a switch at the altar, convenient story opt outs and so forth.
Initially the book was intriguing with poor Merry trying to ease herself into English society and learning how her uncouth "American" ways make her a fish out of water. But overall the book is terrible. Her intended seems like an okay guy and then we see that is not quite so. Same with his brother, who appears to be a gentleman hero that we're all rooting for and all but then becomes a jerk after a particular event. This seemed to be less of character development (or even a reasonable portrayal of the filters coming off after the relationship has begun) but more plot driven than anything else.
There's also a rather convenient switch that helps eliminate an aspect of this love triangle and again, seemed to come out of nowhere only for a convenient (it seems) reconciliation at the end. More plot device (of which there wasn't much) than anything else.
The book is also badly paced. There's a wedding that threw me off because it happened sooner than I thought it would and I wondered what else the author had in mind. Turns out this was just an excuse to write a bunch of super cringe-y sex scenes that makes what's left of the book into a PWP (porn without plot) "romance" that I hate.
So, as you can see, this completely didn't work for me. Don't bother!
