Grace Livingston Hill 
Brentwood [EPUB ebook] 

Marjorie Wetherill had always known she was an adopted child; her adoptive parents, the Wetherills, whom Marjorie loved deeply, had made no secret of it. Their death leaves Marjorie well provided for but terribly lonely. Soon she is consumed with the desire to find the family she has never known. But how can she find them when she knows nothing about them—and when Evan Brower, her handsome, wealthy neighbor, seems determined to make her forget about her unknown family entirely?
Then Marjorie finds a letter from Mrs. Wetherill, written shortly before her death, in which she tells Marjorie her real father’s name and last known address! And so Marjorie’s search begins—a search for a family to call her own; a search that will ultimately change her life and bring her a love more wonderful than anything she has ever known.
