Sweet Justice by Mimi Barbour

Cassidy Santino is closing in on the mobsters who murdered her brother and there’s no way she’s giving up her quest for revenge. She’s working at a seedy bar where the gang members hang out so she can dig up information that might lead to finding his killers. When jealous hookers and sleazy barmaids try forcing her to leave, she fights back. For the love of an old rascal who owns the neighborhood gym, she helps train his protégé in the boxing ring. For her sanity, she clings to her relationship with the one man who makes her feel like a woman.

Detective Trace McGuire loses his mother, the person who’s meant everything to him until Cassidy Santino explodes into his life. This chick’s got him so tied up that he’s willing to shirk responsibilities in his job and cut her slack for interfering in his investigation. But when Cassidy keeps putting herself in danger from the lunatic who owns the bar where she works, that’s where he draws the line. Even if she fights him every damn inch of the way. And man… can this girl fight!
