Mary Marston is a novel by George MacDonald. It was written in 1881 and later republished as A Daughter's Devotion. Written at the height of George MacDonald's literary career, the story centers around the life of a simple merchant's daughter. Mary Marston's unswerving commitment to love God and others is contrasted with a backdrop of an array of characters and a complex and sometimes mysterious plot. It is a story of a woman who loves a man and teaches him to change. Not out of his love for her but simply because it was the right thing to do. MacDonald’s portrayal of the characters ranges from delightful to devious. As such, he intended them to serve as models to readers. His message is that all eventually must stand before God.
