Heartsick, by Chelsea CainRead about the other entries on the list.
The twisted, borderline-romantic relationship between detective Archie Sheridan and his quarry, serial killer Gretchen Lowell, is the meat of this thriller. Kidnapped, tortured, and seduced by Lowell—but also spared by her—Sheridan is a broken man drawn back into the fray before he’s ready. His sudden return draws the attention of young and intrepid reporter Susan Ward, and she shadows him into the Portland’s darkest corners. Together they struggle to find their footing, solve the case, and to sever the heartstrings connecting Sheridan and Lowell once and for all. Chelsea Cain’s years as a contributor to The Oregonian certainly informed her choice for Sheridan’s unorthodox partner.
