Sparks fly when 23-year-old New Yorker Bellarina Levitsky lands on the South Carolinian doorstep of 89-year-old Tilly Wilson, a flawed old woman with an unwavering faith in God and a mouth rife with unsolicited advice. The only thing the unlikely pair have in common is waiting for death's door to creak open.

As an adult orphan facing terminal cancer, Bella flees her home to die in peace, but her new landlady has her own ideas. After all, the old woman is an expert on everything. Just ask her.

Refusing to let Bella wallow in self-pity, Tilly makes it her mission to help the young woman spend her last year living outside the lines, squeezing every experience out of life, and finding the three things she has given up on-God, love, and family.
