Mistress Pat is a novel written by L. M. Montgomery. It is the sequel to Pat of Silver Bush, and describes Patricia Gardiner's life in her twenties and early thirties, during which she remained single and took care of her beloved home, Silver Bush. Pat hated changes as much as ever, and found in Silver Bush a refuge where she was shielded from them, but changes happened nevertheless. In the course of eleven years, new servants, new neighbors and new lovers came and went, her brothers and sisters all got married, and life at Silver Bush was no longer as pleasant as before, but Pat clung to her love of it desperately. It was only in the face of horrible disasters that Pat found where her heart belonged for the rest of her life.
