Grace Livingston Hill 
An Unwilling Guest [EPUB ebook] 

Young Evelyn Rutherford, a New York society beauty, is sent to spend the summer with her aunt. When her aunt falls ill, Evelyn resigns herself to spending a boring summer with a neighboring family.
But the Greys are a family of faith, goodness, and quiet happiness—things Evelyn has never known. Suddenly the social life she longed for no longer holds interest. Instead, a new and powerful dream begins to stir within her—a dream that thrills the Greys’ handsome son, Maurice.
But will Evelyn discover an all-important truth about herself—and about God—before Maurice is gone from her life forever?
