Summer is supposed to be fun, but things have never been worse for eight-year-old Jack Bolton and his nine-year-old sister, Emma. Spending the summer with grandparents he has never met is not Jack's idea of fun. And Grandpa bringing horses to the farm has Emma sick with fear. The siblings remember Dad saying, “We can trust God to bring us through anything,” but they are finding it hard to believe God's promises with Mom and Dad so far away. His promises must be Forever Settled in their hearts.
