If the concept of the Probability Engine and worlds splitting into parallel timelines in Destiny Times Three fascinated you, you'll love how The Man in the High Castle imagines a world where the Axis powers won World War II. Dick's novel masterfully explores how small changes in history can ripple outwards, shifting entire realities and challenging our sense of what is possible.

If you appreciated Leiber's probing of destiny, free will, and the nature of reality, The Dispossessed offers a deeply thoughtful look at the clash of ideologies through the eyes of physicist Shevek, whose groundbreaking work on simultaneity could unite or divide two worlds. Le Guin's novel is rich in philosophical musings about freedom, society, and the self.

Leiber's vision of overlapping probabilities comes alive in Miéville's The City & The City, where two cities occupy the same physical space, but citizens must 'unsee' the other. The novel's brilliant plotting and inventive setting will resonate with your taste for realities that coexist and the rules that bind or separate them.

If you enjoyed following multiple interwoven realities and the mind-bending twists of Destiny Times Three, Permutation City will draw you into a world where consciousness, simulation, and identity are constantly questioned. Egan crafts a complex narrative with several threads that challenge the very nature of existence.

If you relished the unpredictable revelations and shifting realities in Leiber's novel, The Three Stigmata of Palmer Eldritch will keep you guessing at every turn. Dick's story is packed with reality-distorting twists, hallucinations, and sudden reversals that blur the lines between what is real and what is imagined.
