The Year She Disappeared by Ann Harleman

Nan was 60. She is a widow now and enjoying her life after recovering from the grief of her husband's illness and death. She and her only child, Alex, have had a rocky relationship since Alex was young. But one morning Nan receives an urgent phone call from Alex. Nan changes her plans and goes to her daughter's house. Alex tells Nan that her husband Gabriel has been molesting her daughter, Jane. Alex begs Nan to take Jane the next day and to disappear. The plan is for Alex to go to court and get custody while Jane is safe. Their only communication will be through a personal ad in the local paper. Thinking it will only be for a month or so, Nan reluctantly leaves her life behind and boards a plane with her granddaughter. The book kept my attention but I was never that fond of any of the characters! It's worth the read.
