Irish Car Bomb: The Erin O'Reilly K-9 Mysteries, Book 2 (Unabridged‪)‬

If it weren't for the Irish, New York wouldn't have a police force. On the other hand, it might not need one. 

Starting a new job is always stressful, even when bombs aren't involved. NYPD Officer Erin O'Reilly always wanted to be a detective. But on her first day wearing a gold shield, she finds herself investigating the explosive death of a small-time crook. She and her K-9 partner Rolf, together with her new squad of detectives, plunge into a world of gamblers, mobsters, and retired Irish Republican Army soldiers. 

It's an Irish cop against the Irish Mob in an intoxicating cocktail of murder, explosives, and betrayal. Can Erin and Rolf solve the killing before the bomber strikes again?
