A historical romance that main girl hide her gender ?

[Ruzza]

Hi. Could it be The Switch by Lynsay Sands? I know another book that matches your description but I can't remember the name right now. I'm going to look through my books and see if I can find it.

[Ruzza]

Ok found it. Maybe Seduced by Virginia Henley. Hope this helps :)

These Old Shades is just a shot in the dark, though I highly suggest it if you haven't already read it.

Maybe Nine Rules to Break When Romancing a Rake?

I don't recall her acting as a servant, but she does disguise herself as a man and is trying to fulfill a list of things that are acceptable for men to do, which does lead to him sneaking her into his club and the two of them fencing.

Sins of a Wicked Duke has the heroine posing as a man and working as a servant to the hero. Don't remember if she learns to fight, it was a while back I read it.

There's also these listopia lists that might be a good place to look for your book
Heroine Masquerades as a Boy

Women in Pants Heroines

[Aerulan]

If you don't find it on those lists there is also a pretty extensive Cross-dressing and in disguise list on the AllAboutRomance site that might be worth a look.

Oh, Cherry Ripe

Hmm found another one. In this one the heroine is a servent although not to sure about the club part but here you go: The Lady's Secret by Joanna Chambers :)

How to Master Your Marquis by Juliana Gray?

[Kris]

Çiğdem, around what year did you read this book (translated into your language)?

What was the location? Any countries we can rule out?

What was the time period?

Why did she hide her gender - dress like a man?

Any other details - her family, companions, personality of the hero and heroine, etc.?
