If you were captivated by the way Kalki weaves together apocalyptic prophecy and religious symbolism through the messianic figure of Kalki, you'll love Lord of Light. Zelazny's novel reimagines Hindu mythology as advanced technology on a distant planet, where gods and mortals clash in a brilliant fusion of spirituality and science fiction. The protagonist, Sam, challenges divine authority and questions the nature of godhood, echoing Vidal's provocative exploration of faith and messianic charisma.

If you enjoyed the morally ambiguous characters in Kalki, especially Teddy Ottinger and the titular Kalki himself, you'll be drawn to the protagonists of American Tabloid. Ellroy's novel plunges you into the dark underbelly of American history, following deeply flawed operatives as they manipulate and are manipulated through the events leading up to the Kennedy assassination. The characters' questionable ethics and personal motivations make for a riveting, challenging read.

If the dystopian, satirical critique of modern society in Kalki struck a chord with you, The Handmaid's Tale will resonate even more. Atwood's chilling vision of a theocratic future scrutinizes gender, power, and control through the eyes of Offred, immersing you in a world where personal freedom is sacrificed to ideology. Like Vidal, Atwood uses speculative fiction to challenge societal norms and provoke reflection.

If you appreciated the darkly comic tone and satirical edge of Kalki—from Vidal's irreverent treatment of apocalypse to the absurdity of mass movements—Catch-22 will be a perfect follow-up. Heller's classic novel lampoons the madness of war and bureaucracy with the same kind of clever, biting wit, centering on the endlessly frustrated Yossarian and his fellow airmen.

If you found yourself drawn to the philosophical undercurrents and speculative questions about society, destiny, and human nature in Kalki, then The Dispossessed is a must-read. Le Guin's novel follows the physicist Shevek as he challenges the boundaries of two contrasting societies, raising profound questions about freedom, utopia, and the cost of revolution.
