Harper Scott's older sister, June, took her own life a week before high school graduation, leaving Harper devastated. So when her divorcing parents decide to split up June's ashes, Harper steals the urn and takes off cross-country with her best friend, Laney, to the one place June always dreamed of going—California.

Enter Jake Tolan, a boy with a bad attitude, a classic-rock obsession…and an unknown connection to June. When he insists on joining them, Harper's just desperate enough to let him. With his alternately charming and infuriating demeanor and his belief that music can see you through anything, he might be exactly what Harper needs. Except…Jake's keeping a secret that has the power to turn her life upside down—again.
