My review is going to have two parts.
PART 1 - complaints in terms of historical romance.
I might be biased by my favorite (mf) hr authors Mimi Mathews, Mary Balogh, Anne Gracie, Kate Harper or Martha Keyes, but the writing style in this book is totally different from those authors' books, and very much modern. The whole feeling of the book is that of a contemporary romance. The story takes place in 1857 says the first chapter. But the author uses many words/terms usually not used in hr. "Yeah" for example, Merriam-Webster says it's first been used in 1863, other sites say it's been used from 1905 on and originated in American English. According to Merriam-Webster, "chummy" was first used in 1884, "lifestyle" was first used in 1915, "gelato" was first used in 1929, and so on.
The girls drink constantly wine, champagne, brandy, scotch and whiskey at the balls and other formal occasions, but in hr I never encountered that, weren't girls just allowed to drink ratafia and forbidden to drink anything stronger? Then there was a scene where their widowed parents were feeding each other oysters in a restaurant? In 1857? Everything felt so very casual and pulled out of the historical context.
BUT since the blurb explicitely says "A swoon-worthy debut queer Victorian romance (...) the lesbian Bridgerton/Parent Trap you never knew you needed!" I guess maybe the author deliberately chose to write a contemporary romance set in 1857 for readers who haven't a full library of historical romances to compare this book to? And didn't just too little research? I would have loved a heads-up or note at the beginning of the book to clarify it, though (then I would have been able to stay in the story).
PART 2 (the storyline, very mild spoilers)
The first 60% of the story were sweet and it was lovely to watch the two MCs Beth and Gwen falling in love.
Although I understood where Beth was coming from emotionally, I felt really bad for how long she accepted Lord Montson's courtship, because he was a nice person and didn't deserve her lies.
When the sort-of third act break up at 60% occured, I didn't understand why the girls suddenly didn't think anymore of their initial plan for Beth and her mother to be safe without Beth having to marry? The possibility of Gwen's father marrying Beth's mother had been for the first 50% of the book the main goal for the girls, getting their parents to fall in love. Suddenly between page 220 and 285 they forgot all about that? Gwen's father getting drunk with Gwen at a ball (Gwen vomiting afterwards from the carriage's door) and both getting drunk together a few days later at a horse race (Gwen vomiting afterwards at home on the stairs) was a very strange and cringey choice, too, during those 65 pages.
But yeah, fast forward 65 pages of pining and suffering and sadness for all 4 of them and drinking for 2 of them, suddenly the girls remember what had always been their goal!! Make it make sense please (beside the obvious need to lengthen the book) *insert eye roll*.
The end of the book was drama, drama, drama. Disappointing.
Tldr: contemporary YA FF romance disguised as historical romance. Sweet falling in love first half, OTT dramatic will-they-won't they second half of the book.
I'm not anymore curious about the second installment (although the epilogue tried very hard to set the scene for it).
