An old friend sends an ominous warning to Abbott — her enemies have returned to weaken her by any means necessary. As the personal losses mount and her efforts at the newspaper are blocked, Abbott finally catches a break — uncovering one of the most guarded secrets of the group aiming to take down the man who would be Detroit’s first Black mayor. But all victories come with a cost…and this one may be too high for Abbott to pay!
