In page Martin Eden:

"

When Jack London wrote Martin Eden at age 33, he had already achieved international acclaim with The Call of the Wild, The Sea-Wolf and White Fang. Despite the acclaim, London quickly became disillusioned with his fame and set sail through the South Pacific on a self-designed ketch called the Snark. On the grueling two-year voyage—as he struggled with tiredness and bowel diseases—he wrote Martin Eden, filling its pages with his frustrations, adolescent gangfights and struggles for artistic recognition.
