Finding Mrs. Ford

Mrs. Ford leads a privileged life. From her Blenheim spaniels to her cottage on the coast of Watch Hill, Rhode Island, she carefully curates her world. Hair in place, house in place, life in place, Susan Ford keeps it under control.
Early one morning in the summer of 2014, the past pays a call to collect. The FBI arrives to question her about a man from Iraq—a Chaldean Christian from Mosul—where ISIS has just seized control. Sammy Fakhouri, they say, is his name and they have taken him into custody, picked up on his way to her house.
Back in the summer of 1979, on the outskirts of a declining Detroit, college coed Susan meets charismatic and reckless Annie. They are an unlikely pair of friends but they each see something in the other—something they'd like to possess. Studious Susan is a moth to the flame that is Annie. Yet, it is dazzling Annie who senses that Susan will be the one who makes it out of Detroit.
Together, the girls navigate the minefields of a down-market disco where they work their summer jobs. It's a world filled with pretty girls and powerful men, some of whom—like Sammy Fakhouri—happen to be Iraqi Chaldeans.
What happened in that summer of 1979 when Susan and Annie met? Why is Sammy looking for Susan all these years later? And why is Mrs. Ford lying?
