Altered Frequency (Hauntings at Inner Harbor #2)

After losing her father and brother in the line of duty, Missy Prescott vows never to get involved with anyone who has a dangerous job. Blessed with a golden voice, she takes a job as a disc jockey with her own late-night lovelorn dedication show on a popular radio station in Baltimore.
Blake Decker has never had a family. He has come to count on the only family he knows—his brothers on the police force. He’s a one-night-stand kind of guy when it comes to relationships.
Betty McAllister, the caring woman who used to live in Missy’s apartment, is now a ghost. She refuses to cross over until Blake—whom she viewed as her own son—is happily in love. She thinks Missy is the perfect girl for him.
Missy and Blake need to keep each other at a distance as they work together to help Betty find a way to cross over. But when danger lurks, will Missy and Blake lose everything?
