Fresh off solving a murder that hit too close to home, Mack's trust is shattered. But when Milwaukee police detective Duncan Albright asks for her help with a shooting, she can't resist using her extra-perceptive senses to benefit others. It turns out the victim was the ruthless businessman their friend Mal was investigating undercover. And now Mal is missing--and his fingerprints are on the gun. Was his cover blown, forcing him into hiding? Or could he be a straight-up killer on the run? Mack doesn't know what to believe anymore--except her own gut, which leads her to secret rooms, shocking revelations... and the fear that this could be her final round.
