A young mother haunted by war, determined to make a fresh start. But sometimes, the sins of the past aren’t so easy to escape.

Recent Afghan refugee Kamela Ahmadi was last seen exiting her place of work three weeks ago. The local police have yet to open a case, while her older, domineering husband seems unconcerned. Kamela’s closest friend, however, is convinced Kamela would never willingly leave her three-year old daughter. At her insistence, missing persons expert Frankie Elkin agrees to take up the search through the broiling streets of Tucson. Just in time for a video of the young mother to surface—showing her walking away from the scene of a brutal double murder.
A riddle wrapped in a mystery inside an enigma.
Frankie quickly realizes there’s much more to the Ahmadi family than meets the eye. The father Isaad is a brilliant mathematician, Kamela a gifted linguist, and their little girl Zahra—she has an uncanny ability to remember anything she sees. Which given everything that has happened during the girl’s short life, may be a terrible curse. When Isaad also disappears under mysterious circumstances and an attempt is made on Zahra’s life, Frankie realizes she must quickly crack of the code of this family’s horrific past.
A lock that has no key for a key that has no lock.
Someone is coming for the Ahmadi’s. And violence is clearly an option. When everything is on the line, how far would you go to protect the ones you love?
Frankie is about to find out.
