The year of goodbyes and hellos : a novel / Kelly Irvin.

Enhanced descriptions from Syndetics:

In a novel inspired by the author's own cancer experience, two sisters seek a new balance in work, family, 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 as 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.

The Year of Goodbyes and Hellos is a novel that will have readers reaching for the tissue box again and again as the author uses her own experience of living with ovarian cancer for seven years (and counting) to provide first-hand knowledge of sitting in the chair when the diagnosis is first delivered and the repercussions that follow.
