My Fair Concubine (Tang Dynasty #3)

The Nobleman Who Turned a Tea Girl Into a Princess...

Yan Ling tries hard to be servile—it's what's expected of a girl of her class. Being intelligent and strong-minded, she finds it a constant battle.

Proud Fei Long is unimpressed by her spirit—until he realizes she's the answer to his problems. He has to deliver the emperor a "princess." In two months can he train a tea girl to pass as a noblewoman?

Yet it's hard to teach good etiquette when all Fei Long wants to do is break it, by taking this tea girl for his own...  Rated '3/5 - Open door' for steam/spice/heat level.
