Former child music prodigy Lily Croft spends most days in her home office crunching numbers and analyzing data as an actuary. Once she filled concert halls across the world, until the pressure got to be too much and forced her retreat. When her boss hands her a temporary assignment, Lily has to leave the safety of working from home to work with people at an office. She keeps her head down and stays focused, but one night on her way to the train station, she hears music wafting from The Leading Note and the life and feelings she suppressed for over a decade bubble up to the surface.

Lily is inexplicably drawn to Hope D'Marco, Leading Note's gorgeous and brilliant founder. But falling for Hope and re-exploring her passion for music force Lily to face her past. Will she go back into hiding, or have the courage to confront the consequences of her past and present colliding?
