Changing Her Tune (Barlow-Barretts #5)
Laura Browning

Pippi’s taking a sabbatical from her music studies to help her ailing father. If that means spying on one really hot guy, she’ll do it. The problem is she likes what he has to say and likes him even more. When her sense of honesty forces her to resign her job, she overhears a scheme that will put her life in danger, and now it’s Phillip who must keep an eye on her.
Falling in love wasn’t in either one of their plans.
