He is best known for the epic fantasy series A Song of Ice and Fire, whose published books include A Game of Thrones, A Clash of Kings, A Storm of Swords, A Feast for Crows, and A Dance With Dragons. The novels follow rival noble houses, shifting alliances, and multiple point-of-view characters across Westeros and beyond.
HBO adapted the series as Game of Thrones (2011–2019), a Primetime Emmy Award–winning drama, and later as the prequel House of the Dragon (2022–present). Martin also wrote the related Tales of Dunk and Egg novellas. Outside that setting, he helped create the long-running Wild Cards shared-world anthology series and contributed worldbuilding for the video game Elden Ring (2022). His work spans prose fiction, screenwriting, television production, shared-world anthologies, and game worldbuilding.
