The book's structure challenges conventional narrative, mirroring the clever temporal leaps that made Heinlein's story so compelling.

If you were intrigued by the way All You Zombies explores destiny, personal agency, and the paradoxes of selfhood, Kindred will resonate deeply.

The novel forces her—and you—to grapple with the limits of free will and the haunting consequences of time travel, much like Heinlein's protagonist confronting their own origins.

If the shocking plot twists and revelations in All You Zombies left you breathless, The Prestige will keep you guessing until the final page.
