Lying with the Devil by Lindemann, Lana

Mary is your typical student, your typical homebody. She doesn't know what to do with her life and doesn't expect much out of the days to follow until things suddenly change for her. A serial killer is on the loose and kidnaps her off the streets with the intent of ending her life. But then his plans change. Instead, he keeps her like a pet, chained up in his apartment.
Abuse follows as well as the manipulative games he plays. He toys with her, slowly diminishing the hope she has at being found and at being saved, while his own feelings of what seem to be love begin to blossom for her. All while he battles his own urges-it's them or us.
Kole, Mary's brother, searches for her with the help of Steven and Carl, two detectives frantically running into dead ends with what little clues this killer leaves behind.
Can Mary survive, even as Stockholm syndrome begins to take hold?
If Kole finds her, will she ever be the same?
Enjoy this psychological thriller set in the 1980s, said to be gripping and emotional that will leave you turning pages until the very end.
