Black Karma — Thatcher Robinson

Bai Jiang -- San Francisco's best-known souxun (“people finder”) -- is hired to track down the mysterious Daniel Chen. Police inspector Kelly suspects Chen of being involved in a botched drug heist that resulted in the death of an officer. Bai has her own suspicions.  She thinks the police just want to see Chen dead.  

Her investigation leads Bai into deadly intrigue as she finds herself caught between international intelligence agencies and merchants of war, who deal in death, drugs, and high-jacked information.  

To make matters worse, she's thirty-something and dating again. It's not easy juggling a suitor with family connections, a brazen young man who finds her irresistible, and her ex--the father of her child. 

World conflict and family strife explode as adversaries face off in San Francisco's Chinatown, a world away from the one we know.
