Some scars run deeper than others
Detective Erin OβReilly is no stranger to close calls. She and her K-9 Rolf have dodged more than their share of blades, blasts, and bullets as theyβve taken on the worst New York City has to offer. But the last perp came a little too close, leaving one of Erinβs fellow officers with a bullet-hole in his head and her own brain scrambled.
Erin needs a break, but as her long-running infiltration of the OβMalley gang enters its final act, she canβt afford to slack off. And thatβs not her only headache. When a former convict turned pizza deliveryman has his skull crushed in a college parking garage, an apparent mugging may be something much more sinister. Banging her head against one problem after another, Erin faces obstacles both on the street and in herself. Sheβll have to break through to the answers before her own brain lets her down.
