The Gangster's Kiss - Love is a Dangerous Thing, #1

John O'Malley's sister is missing. All the clues of her disappearance lead to Hayward County, Wisconsin and the crooks and questionable sheriff that reside there. Pretending to be one of them, John takes a job as bodyguard for the sheriff's beautiful sister, Grace. It seems like the perfect way to investigate their crimes and corruption, but when someone threatens to kill Grace, the job proves harder than he thought.
Is she an innocent witness to a crime, or just as guilty as everyone else? Grace Sullivan just wanted a normal life: find a good man, get married and have a family. She has had enough of looking the other way while her brother hides behind his sheriff's badge to conduct shady dealings. Hiring a gangster named John to watch her is the final straw. When a face from the past threatens her life, she is forced to put her life in John's hands, but as time goes on, all she really wants is to be in the gangster's arms.
