Mori 
Duchess in the Attic: Volume 2 [EPUB ebook] 

Opal moves to the Taisei Kingdom with her beloved and childhood friend, Claude. While her new husband had made a name for himself in Taisei, they both know their new home doesn’t take kindly to foreigners. Behind the shimmery glamour of aristocracy lies nasty gossip and misogyny; they view Opal as a wanton woman! But Opal is nothing if not stubborn, and she won’t let these bullies have their way with her! She’s got a keen mind and a sharp tongue, and she’s not afraid to fight back.

All the while, trouble looms: a letter from the king has Opal finding her beloved…in bed with another woman?! It can’t be! He isn’t the type to commit such a horrible act! Opal hasn’t married an adulterer… Or has she?!
