A serial killer is loose in Chicago. She’s also the city’s top forensic psychiatrist. An expert on criminal deviance, Donovan Montgomery has given testimony that locked up the city’s worst gangsters. Yet this brilliant, beautiful African-American woman is losing the war against her inner psychological demons. Increasingly, she perceives a universe gone crazy, especially the insane breakdown of the justice system she’s sworn to uphold. She begins to see it as her mission to set things right—even if it means killing to do so. The story opens with Donovan, along with hundreds of innocent bystanders, under sniper fire in Daley Plaza. Thirty-two people are slaughtered. To make matters worse, the Windy City is already on edge as a white nationalist runs for congress and Mason Ghetz, a member of the Aryan Brotherhood, stands trial for the murder of three black men. Despite death threats, as the state’s expert witness Donovan is determined to put Ghetz away for life. But things go horribly wrong. Donovan’s world is suddenly upended, her inner killer unleashed. Now on a personal vendetta, she plunges into the city’s underworld, an asylum of corruption, conspiracies, and madness. Just the kind of world for Donovan to make it right.
