Replaced Parts by Stephanie Hansen (Book Review #2145)

Stephanie Hansen’s Replaced Parts is a heart-pounding YA sci-fi adventure that combines interstellar intrigue, ethical dilemmas, found family, and fearless rebellion. Set in the year 2163 under the shadow of a tyrannical World Government, the novel follows sixteen-year-old Sierra—a bold and passionate activist—on a high-stakes mission to rescue her father. But the moment she and her online best friend Yesha (aka Vienna) set foot on Planet Vortex, they uncover horrors that stretch far beyond animal testing.

From sentient alien guards forced into servitude to twisted scientific experiments that turn scientists into lab rats, Hansen’s vivid world-building delivers both action and depth. The sinister Cromwell—bent on resurrecting his cryogenically-frozen wife and child—emerges as a complex villain whose desperation is as human as it is horrifying. The emotional tension soars as Sierra is offered an impossible choice: sacrifice herself to protect those she loves or watch the revolution crumble.

What sets Replaced Parts apart is its perfect fusion of thrilling plot twists, emotional vulnerability, and ethical questions. Hansen’s strength lies in her diverse, emotionally resonant cast—Al, the quietly brilliant love interest; Albina and Viscerous, her loyal allies; Colsam, the morally awakened alien guard; and Aviator, a majestic vulture who soars into our hearts as a surprising symbol of hope and loyalty. Their bonds bring light into the story’s darkest corners.

The novel is deeply imaginative and sharply written, with a jaw-dropping twist and a clone-fueled cliffhanger that ensures readers will anxiously await the next installment. Hansen writes with the clarity of an experienced world-builder and the empathy of someone who understands the value of representation. As a member of the deaf and hard of hearing community, she naturally infuses inclusion into her storytelling, making Replaced Parts as meaningful as it is entertaining.

A must-read for fans of Cinder, The Hunger Games, and Skyward, Replaced Parts delivers a pulse-pounding, emotionally resonant ride through betrayal, bravery, and the futuristic cost of love.
