Ace of shades

Raised as a proper lady, Enne Salta must abandon her reputation and leave her finishing school to look for her missing mother in New Reynes--also known as the City of Sin. The only lead she has is a grifter named Levi Glaisyer who needs money to clean up an investment scam he was running. Her offer of financial help to find her mother is just what he needs. But as they search for clues, Enne becomes immersed in a foreign world of gangs, gamblers, and glamorous casinos.
