Does when breath become air mention fiction anywhere in the book?

The author of the book, Paul Kalanithi, mentions fiction in the book When Breath Becomes Air. He develops a love for reading and literature through his mother, who makes Paul and his brothers read books from college reading lists. During this time, he was not too keen on the practice of medicine, as his father was a doctor too. He specifically references reading the book Satan: His Psychotherapy and Cure by the Unfortunate Dr. Kassler, J.S.P.S. (a fictional work by Jeremy Leven), the summer before he starts school at Stanford University. The book is about a messy psychiatrist with many problems in his personal life. Kalanithi also went on to get a degree in English literature as well.
