In Vadhan Bommadevara’s The Gudem Experiment, Sheila Pitambar lives in Gurugram with memories no one else accepts: she had another life in which Chennai lawyer Raghuram Surya loved her, fathered her daughter Diya, and died fighting the Sutram, an ancient force trapped beneath the Surya family memorial hall in Gudem. In the present, Raghu is alive, Diya is nine, and crime lord Govind Kiromal is working with a mutilated tantric to open the hall and use the Sutram for power. When Diya begins seeing deadly moments before they happen, Sheila realizes the child may be able to move through time. To protect Diya, Sheila must bring Raghu into a past he barely remembers and reach Gudem before Kiromal’s men turn the buried force into a weapon.

Vadhan Bommadevara’s The Gudem Experiment makes time travel feel near enough to touch and old enough to carry a soul’s unfinished work. As a reader who loves time travel touched by past-life mystery inside fantasy, I loved how the worldbuilding makes 1971 feel active and sacred, with Gudem castle’s torchlit safety paired with Lucky Homes’ guarded cottage to show how places shape survival. The system is refreshingly direct, using Rathaya’s altered sight as Diya’s anchor into the past, then tying each restored memory to a larger repair that gives every trip purpose through Diya’s urgent secret mission. The characters have a brave, searching vibe that fits the story’s scale. Diya brings nerve and heart to each risk, while Surya Prasad carries royal duty with a moving sense of public honor. Well written and immersive, readers who enjoy Indian-centric speculative fiction will adore this. Very highly recommended.

In Vadhan Bommadevara’s The Gudem Experiment, quantum scientist Sheila Pitambar is plagued by split realities after a traumatic accident in Mumbai. She fought an ancient, world-devouring "Great Danger,” known as the Sutram, in an erased timeline, alongside royal lawyer Raghuram Surya in Gudem, Andhra Pradesh. In her living reality, she is alienated from her nine-year-old daughter, Diya, and divorced from her husband Alok. Her daughter is a gifted child with precognitive visions. People look at Sheila as insane for believing she conceived in an erased reality and gave birth to her current child. When Sutram’s earthly vessels — a ruthless corporate tycoon, Govind Kiromal, and a sinister, half-cleaved tantric — murder Alok and kidnap her daughter to use in harnessing cosmic power, Sheila flees to Hyderabad. The fighters from the erased timeline reassemble: Raghu remembers nothing; Colonel Kant is haunted by “the White;” P. Eshwar is mysterious; Poti is loyal; and Rathaya is the blind witness to the 1971 experiment. Do they have enough fight in them to stop the encroaching darkness?

The pacing in The Gudem Experiment is breathless, mimicking Sheila’s fragmented psyche. From a 2 a.m. meditative vigil to the shattering massacre in an apartment, the tension accelerates. But the short city-stamped chapters make the story enjoyable, mixing quantum physics with Vedic cosmology. The author uses foreshadowing skillfully, giving you a sense of dread about what could happen with Diya’s eerie refrain, “Damned if I do, damned if I don't.” Vadhan Bommadevara’s work examines cosmic destiny, illusion (maya), memory, and sacrificial love. The characters are complex and fully drawn, featuring a resilient mother, a man with exceptional Aikido street-fighting skills, and a colonel struggling with PTSD. This twisty science fiction novel entices with its mythological elements, growing tension, and the compelling heroine.

The Gudem Experiment is the first book in a series by Vadhan Bommadevara. The story follows Sheila Pitambar, a woman torn between two versions of her own life. In one, she's a divorced mother in Gurugram, labeled insane by everyone around her. In the other, a memory that feels just as real, she once fell in love with a man named Raghuram Surya and helped him defeat an ancient, world-devouring evil called the Sutram. However, she lost him in the process of defeating the evil. Nobody believes her, not even her own daughter Diya, who has started repeating a strange phrase in her sleep that terrifies Sheila to her core. As proof of the erased reality starts turning up in her actual life, Sheila is pulled back into the fight against evil. Things take a horrible turn when she learns the key to stopping the Sutram once and for all lies with a man called the extraordinary cripple, a legendary figure who supposedly died back in 1971. But how can Sheila get to him and defeat Sutram before all is lost?

Author Vadhan Bommadevara created something incredible by blending quantum physics with Indian mythology. The novel was a perfectly layered story, and I was hooked from the very first chapter. Sheila is such a compelling protagonist. She is a woman fighting to be believed while carrying the weight of two entire lifetimes on her shoulders. While she fights the world, she has to deal with her grief for the family she lost. I loved how the mystery kept unfolding in layers, every answer about the Sutram or the extraordinary cripple only opening up more questions. The worldbuilding around Gudem and the Surya family legacy is fascinating. Diya, Sheila's daughter, is wise beyond her years and almost counteracts Sheila’s determination with her intelligence. I can tell that Vadhan Bommadevara clearly put his whole heart into this story. The Gudem Experiment truly blew me away, and I cannot wait to see what happens next in the story.

The Gudem Experiment is the first installment in Vadhan Bommadevara’s urban fantasy series and a clever blend of Vedic mythology, science fiction, and quantum physics. Set in 2015, the story follows Sheila Pitambar, who undergoes an unusual experience. She is possessed by haunting memories of a world that no longer exists. And no one will believe her story. Of course, who would think that you can conceive in one reality and give birth in another? Everyone sees her as insane, but she knows differently. She has saved the world from a powerful evil in another reality when she was pregnant and had lost the love of her life in the process. That evil is slowly sneaking into her current reality, and she must fight it again. But she must get help from allies who fought the same evil in the erased reality. How can a man who died in 1971 be the key to defeating the imminent danger?

Vadhan Bommadevara crafts a compelling fantasy that is infused with pathos, creating memorable characters. The book creates an emotionally enticing blend of the mundane and the mystical, examining Sheila's lonely life in the real world and the dreamscapes of a world that haunts her. The treatment she receives constitutes the fodder for the exacting pathos that permeates the writing. The pacing is not hurried, but the suspense persists as the story moves from haunting memories to real-life challenges for the heroine. The Gudem Experiment has love, myth, and a psychologically grounded plot that make it a gripping story. The crisp prose successfully paints the portrait of a woman whose nights are filled with dread and whose mornings are no less horrifying. You are compelled to turn the pages for a satisfying denouement.
