The Wood Beyond the World by William Morris

The Wood Beyond the World is a fantasy novel by William Morris, perhaps the first modern fantasy writer to unite an imaginary world with the element of the supernatural, and thus the precursor of much of present-day fantasy literature.
When the wife of Golden Walter betrays him for another man, he leaves home on a trading voyage to avoid the necessity of a feud with her family. His efforts are fruitless, as word comes to him enroute that his wife's clan has killed his father. As a storm then carries him to a faraway country, the effect of this news is merely to sunder his last ties to his homeland.
