When Rett's stay-at-home husband, Harry, gets the chance to complete his Ph.D. with a renowned scientist, she doesn't hesitate to encourage him go for it—even though his studies will take him far afield. Whatever happens, they're confident their relationship is solid.

But when Rett is abruptly put on leave under suspicious circumstances at her nursing job, and with Harry stuck in the wild of Manitoba, she finds herself navigating treacherous emotional waters without him. And as the weeks pass, they both begin to fear the chasm between them is too deep and wide to bridge.

This third-in-series features sisters who hold each other up through life's everyday challenges, family distractions, dogs, goats, chickens and a nurse who can do it all. Well, almost.
