At the heart of Tracey Garvis Graves's Heard It in a Love Song is the simple, but beautiful message that it's never too late to start over. Still processing her divorce and working to redefine herself beyond her career as a lead singer in a popular band, 35-year-old Layla Hilding is surprised to find she can't stop thinking about the single dad of one of the children in her music class. The good news is he's smitten with her, too.
