Life hasn't been easy for Cady Caldwell, struggling first with her drug-addicted parents, then mistreated by the husband she though would be her savior. But there was always one thing that kept her going: protecting her younger sisters and ensuring their lives are happy. Escaping her abusive marriage, Cady is shunted off to the small town of Garrison, Montana, to live with a paternal grandmother she doesn't know, and doesn't want to. It seems that her two younger sisters, and an equally determined grandmother, are hell bent on looking after her. But can they get her to live again?
