Archibald Caswell could never please his domineering granddaddy Silas. Now with Granddaddy gone, Archie finds himself lost, confused, and wondering what his grandfather could have possibly meant by his dying words: "Young man, you are a saint!"

Clare Simpson knows exactly what Silas meant. She convinces Archie to dedicate his life to God, give up his possessions, steal his granddaddy's truck, and head north to the Cloisters in New York, where she and Archie secretly live after museum hours. For Clare the journey is a return to the only place where she has felt happy and loved. For Archie, the pilgrimage leads him to a closer relationship with God--and a burning desire for home.
