When tragedy strikes just as seventeen year old Harmony Larkin's first single hits the music charts, her whole world falls apart. Sent to live with her eccentric grandfather, she rebels against her new life. To make matters worse, bad boy drummer Cash Holloway, is her granddad's unlikely live-in 'handyman.' With an ego the size of Texas, Cash challenges and annoys Harmony at every turn. Living with this unconventional duo will not be easy for Harmony, yet their offbeat ways might be exactly what she needs to heal her broken heart.
