Maggie O'Brien is tough. She has to be-as a tactical emergency medic for the St. Louis SWAT team and a trauma nurse at Blymore Memorial. The daughter of a violent ex-cop she prefers wits over weapons. Then one of her patients, a psychotic former FBI agent known as Montana Bob, dies in the ER from superficial wounds following a botched stand-off-but not before revealing a secret about Blymore...It's called The List-a chillingly precise run-down of expendable citizens and patients. And one by one, under Maggie's care, they're dying from inexplicable causes. With each one comes another step in framing Maggie...with each step comes Maggie's fear that no colleague or friend is above suspicion-including her lover, police officer Sean Delaney. With no one left to trust but herself, her investigation takes her into the darkest recesses of a killer's mind bent on a vengeance that targets Maggie as the final victim.
