Special Agent K

Special Agent K-Feng, aka Khloe Feng, was on a top-secret mission when the accident happened. When she woke, she was in another time, another place, another body. By day, she’s the illegitimate daughter of a noble family. By night… she’s the Xia Kingdom’s most hyper-lethal assassin. She can dispatch targets in a single bloody blow, but can she survive being a courtly lady too?
