London's novel about Buck, a domesticated dog stolen from California and thrown into the Yukon gold rush, where he gradually reverts to wildness. Written in 1903, it remains the most visceral exploration of the animal self buried inside domestication.

London's novel about a literary critic shanghaied aboard a sealing schooner captained by Wolf Larsen — a Nietzschean brute who reads Herbert Spencer between beatings. The Pacific Ocean as a classroom in survival of the fittest.

The inverse of The Call of the Wild — a wolf-dog hybrid moves from wilderness to domestication. London exploring the same territory from the other direction.
