My friend Jessica has been after me to read Tana French's Dublin Murder Squad books for a few years, and I don't know why I waited so long.
The coolest thing about this series is that each novel focuses on a minor character from the last novel, so you begin to feel like you're really getting the full spectrum of plot development, and each book works as a stand-alone installment.
This book focuses on police detective Mick Kennedy, who is called to the failed suburban dream home community of Broken Harbor to investigate the horrific murder of a father and two children. Only the mother was left alive, and it quickly becomes clear that someone had been watching the family closely prior to the homicide. Kennedy also has a troubled past concerning Broken Harbor, and he begins to feel old ghosts pressing in on all sides as he tries to solve the case.
This was so good that I'm going back to read all the rest of the books in the series. New author obsession: check.
