Shadow of the Knight — Susan Lee

Mickey Lenz never saw herself as someone who needed rescuing, not even after a suicide attempt. She rebuilt her life and found comfort in structure and in the comic books she read and created. And with the prospect of something romantic on the horizon, life was becoming damn good. Until Mickey is attacked one night, and becomes convinced that a hero in a bat suit rescued her. An obsession develops as Mickey puts herself in dangerous situations, hoping her bat will come and save her. When her nightly prowlings don't result in a rescue, her adventures take a dark and savage turn, with tragic consequences.
