On October 16, 1965 Abbey married Judy Pepper, who accompanied Abbey as a seasonal park ranger in the Florida Everglades, and then as a fire lookout in Lassen Volcanic National Park. Judy was separated from Abbey for extended periods of time while she attended the University of Arizona to get her master's degree. During this time, Abbey slept with other women—something that Judy gradually became aware of, causing their marriage to suffer. On August 8, 1968 Pepper gave birth to a daughter, Susannah "Susie" Mildred Abbey. Ed purchased the family a home in Sabino Canyon, outside of Tucson. Judy died of leukemia on July 4, 1970, an event that crushed Abbey, causing him to go into "bouts of depression and loneliness" for years. It was to Judy that he dedicated his book Black Sun. However, the book was not an autobiographical novel about his relationship with Judy. Rather it was a story about a woman with whom Abbey had an affair in 1963. Abbey finished the first draft of Black Sun in 1968, two years before Judy died, and it was "a bone of contention in their marriage"
