Heartsick Publisher's Summary
When another killer begins snatching teenage girls off the streets of Portland, Archie has to pull himself together enough to lead the new task force investigating the murders. A hungry young newspaper reporter, Susan Ward, begins profiling Archie and the investigation, which sparks a deadly game between Archie, Susan, the new killer, and even Gretchen. They need to catch a killer, and maybe then, somehow, Archie can free himself from Gretchen, once and for all.
Either way, Heartsick makes for one of the most extraordinary suspense debuts in recent memory.
