The Fall of the Towers is a trilogy of science fantasy books by American writer Samuel R. Delany.

Delany describes the extent of the rewriting in a final note in the one-volume text.

The stories of the Fall of the Towers trilogy were originally set in the same post-holocaust Earth as Delany's earlier The Jewels of Aptor; however, linking references were removed in later revised editions.

[3] The trilogy follows the journey of Jon Koshar, a man who awakens to find himself in a new world and sets out on a quest to uncover the secrets of the mysterious Towers that dominate the landscape.

Along the way, he meets mutants and telepaths who help him navigate a dangerous political landscape and overthrow the ruling elite.
