It's the duet of a lifetime when a rock star and his backup singer find a new kind of harmony off stage in this sensational contemporary romance.

Clementine Clark isn't looking for love. Growing up with a single mom who weeps over a new guy each week tends to have that effect on a girl. But Clementine doesn't mind being the rational one-she's even buried her musical dreams so deeply within herself that she hardly notices the hole it's left in her life.

That is until her best friend calls her with a life-changing opportunity: to join Irish megastar Halloran on his first US tour as a backing vocalist. Clementine wants to reject the offer, but the pay is enough to change her and her mom's life. Overnight, Clementine goes from serving enchiladas at the Happy Tortilla to belting high notes before a cheering crowd.

But the whiplash of trading small-town Texas for sold-out stadiums is nothing compared to the rush of performing with the enigmatic Thomas Patrick Halloran. Poet, introvert, and lyrical genius, Halloran quickly gets under Clementine's skin. The two couldn't see the world more differently. 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?
