What's Mine's Mine is a Christian fiction novel written by George MacDonald, a Scottish author, poet and Christian minister. He was a pioneering figure in the field of fantasy literature and the mentor of fellow writer Lewis Carroll. In addition to his fairy tales, MacDonald wrote several works on Christian apologetics. 

Set in the invigorating wilds of Scotland, clans are crumbling and emigrating as their homeland is bought out from under them. The characters quickly become your friends as you identify with and learn from their struggles and joys. Contrasts abound between true and false (or shallow) relationships, convictions, morals, and faith.
