The Promise of Tomorrow - Mary Ellen Taylor

From the author of The Brighter the Light comes the moving story about one woman's reason for leaving home and the love that brings her back.
When Olympia leaves her small Virginia town, she doesn't expect to look back, much less ever come home. But after a year on the road, her sister's engagement pulls Olympia into everything she left behind: her family, her husband, and the grief she's been trying to forget.
She's determined to stay a few days, maybe a week-just enough time to visit gravestones and sign off on the divorce her husband, Spencer, asked for. But he's reeling from their shared loss, as well as complications with his aging parents, leaving his heart just as fragile as Olympia's. The more time they spend in each other's orbit, the less sure they are they'll be able to walk away for good.
As family secrets come to light and family bonds stretch to the breaking point, Olympia must decide where she's going next and where she belongs. She's used to coping with life's complications alone, but maybe the best way to heal is together.
