Two sisters work to heal lingering childhood wounds and seek a new balance in work, family, marriage, and love when one receives a diagnosis that sets the clock ticking.

Determined to save Sherri's life, Kristen drops everything to guide her sister on the harrowing cancer treatment journey. When she's unable to balance the strain of caring for her patients, being a wife and mother, and her frantic efforts to save her sister, Kristen's carefully balanced life crumbles, starting with her marriage. Desperate to regain her footing, she vows to rebuild her broken relationships . . . as soon she's sure Sherri will beat the odds stacked against her.

Unlike her sister, Sherri Reynolds has worked to cultivate balance in her life. Her children, her job as a teacher, and her strong faith keep her grounded—until her diagnosis sends her spiraling into the scary world of what-ifs and unknown outcomes. Sherri faces the agonizing realization that family history may be about to repeat itself. With the clock ticking, she's determined to use whatever time she has left to heal old wounds and restore relationships.

Together, the sisters are forced to reexamine their priorities, address the still tender wounds of their childhood, and delve more deeply to discover what it means to live each day to its fullest.
