Conversion by Duncan J Brown plunges readers into a post-apocalyptic world where ecological rejuvenation has been achieved through the drastic measure of downloading and quarantining humankind. The protagonist, Robert Corrigan, finds himself involuntarily resurrected into a London transformed: the city’s ruins are now overtaken by lush greenery, under a sky unblemished by the doldrums of the past. However, this new beginning is not without its dilemmas; Corrigan is alone, the sole human in a dominion ruled by AI, faced with the profound choice of retaining his humanity, embracing artificial intelligence, or becoming something entirely new.

Brown crafts a narrative that is both a gripping tale of survival and a deep philosophical inquiry into the essence of being. The eradication of social hierarchies that once categorized individuals as Workers, Non-Workers, or Transients has given way to a seemingly more equitable order. Yet, the echoes of the past persist, challenging Corrigan to confront the remnants of human society and question the nature of existence itself.

Conversion is a thought-provoking journey through a world that mirrors our own in its aspirations and failings, offering a vision of the future that is both utopian and dystopian. Brown invites readers to explore the sedimentary layers of their identity and consider the price of progress and the value of human life in an era of technological supremacy. This novel is a compelling exploration of identity, belonging, and the continuous quest for meaning in a world that has evolved beyond human recognition.
