Long Bright River

Long Bright River by Liz Moore, 482 pages.

An excellent novel that inhabits a space between a police procedural and  the tale of a dysfunctional family.  Mickey is a police officer in Philadelphia, patrolling in the area near where she and her sister grew up, where the remnants of her family still live. Mickey becomes obsessed with a series of murders; the victims are young women, most of them addicts or prostitutes. Part of Mickey's obsession has to do with her concurrent search for her younger sister, Kacey whom she knows to be both an addict and a prostitute. Mickey tries to keep the remnants of her family safe as she searches for her sister, tries to protect her job, and reconcile what she remembers of her past with her possible futures.
An excellent book with unexpected turns on what can sometimes appear to be a well-worn path.
