Samantha Rushford’s future looks bright: the high school art teacher is getting ready to leave Mirror Lake and move to Boston with her ambitious boyfriend, and she hopes a diamond ring is just around the corner. But her past still has a hold on her—especially the bittersweet memory of her rebellious ex, who kissed her passionately before he left town without a word.Since then, Lukas Spikonos has parlayed his rebel ways into life as an up-and-coming recording artist. When he shows up for a surprise gig at the high school prom, Sam is more dumbstruck than starstruck—he used the words of a poem she wrote about their breakup to create a number one hit. But Lukas hasn’t returned just to impress students; he’s facing some real-life responsibilities and needs Sam’s help. But she has her own unresolved issues about the life she wants to lead. Will the music—and the pull of true love and family—put their hearts back in harmony?
