Singer-songwriter Kenzie McCall thrives on freedom-writing what she wants, when she wants, for whoever she wants, with no strings attached. Deadlines? Not her thing. Commitment? Even less so. But when a movie studio offers her best friend, pop sensation Braxton, a starring role if Kenzie writes the theme song, she reluctantly agrees. There's just one catch: the song has to be about love, and Kenzie has never truly fallen for anyone.

Rachel has life mapped out: white picket fence, two kids, a dog, and a marriage filled with spark- and is determined to find someone who wants the same future. When Rachel hears Kenzie sing for the first time, the connection is instant, electric, and impossible to ignore. But how can she plan a future with someone whose life is anything but stable? Kenzie is constantly jetting off to meet with celebrities, and Rachel's cozy suburban dream feels like Kenzie's worst nightmare.

Will they be able to write their love story together, or are they destined for different endings?
