A Song of Ice and Fire — George R.R. Martin

George R.R. Martin's A Song of Ice and Fire (1996-ongoing) radicalised epic fantasy by applying genuine historical complexity — political realism, moral ambiguity, and author willingness to kill beloved characters — to genre conventions. Its HBO adaptation Game of Thrones became a global cultural phenomenon, and the still-unfinished series remains the most ambitious narrative in contemporary fantasy. Outperforming #2's marketing reach, Martin's world has spawned over 90 million copies sold worldwide, with the average novel length exceeding 1,000 pages.
