"Richard Allen, a composer, and his wife Keisha Johnson, a historian, are happily married and raising two bi-racial teenagers in 2019 when they become a grim statistic: one of Chicago's 510 families to lose a close relative to murder that year. In her devastating grief, Keisha finds a lifeline -- searching for the biological father she never knew. That search leads her into the dark history of police relations with Black people in Philadelphia in the late Seventies and Eighties. It also leads her to her birth father's Jamaican-American family."--Publisher marketing.
