The Merge: A Novel by Grace Walker is a dystopian sci-fi debut about a controversial technology that merges two people's consciousness into one body, marketed as a solution to overpopulation and climate change. The story follows several pairs, including a mother with Alzheimer's and her daughter, as they undergo the experimental procedure, questioning its true nature and the ethical implications of identity, love, and control. It's often compared to Black Mirror for its thought-provoking and dark themes.
