Warlock o' Glenwarlock

"Warlock o' Glenwarlock: A Homely Romance" by George MacDonald

George MacDonald was a Scottish author, poet, and Christian Congregational minister who went on to become a pioneering figure in the field of modern fantasy literature. This tale follows Laird Warlock and his son Cosmo who are being crushed under the debts of their ancestors. When their neighbor offers to buy their debt, it's tempting, if not for the fact that their property would go to him as well.
