Clementine Clark isn't looking for love. She's a talented singer, but she's set her dreams of stardom - and romance - aside to care for her ailing mother. And then her best friend calls her with a life-changing opportunity: join Irish megastar Halloran on his first US tour as a backing vocalist.Clementine wants to reject the offer, but the pay would change her and her mom's life.

And yet, over the course of the next eight weeks on tour, the romantic rockstar might just strike an unforgettable chord in Clementine. But will it be enough for an encore?
