5/5 Review from Readers' Favorite:

Minimum Safe Distance is a work of fiction in the science fiction, alien first contact, and interpersonal drama subgenres. It is best suited to mature readers owing to some scenes of violence and was penned by author X. Ho Yen. The author presents a unique take on first contact with highly advanced aliens observing Earth. As humanity faces the consequences of its mistakes, the aliens grapple with ethical dilemmas over intervening in a cosmic threat. The story weaves a complex narrative involving governments, brilliant AI experts, and anti-secular zealots, all influenced by the alien agenda. The result is a truly mind-bending experience, blending speculative fiction with ethical considerations.

Author X. Ho Yen has lovingly crafted a detailed and well-considered exploration of human nature, ethics, and the consequences of advanced technology that makes for both entertaining and thought-provoking reading from cover to cover. The character portrayals are vivid and diverse, and I was particularly impressed by the clashes between the neurodivergent AI expert and the violent zealot, representing opposing forces within humanity with intriguing dialogue exchanges and very tense scenes. The plot twists keep readers engaged with the smaller picture of these day-to-day interactions, and the philosophical questions raised by the overarching storyline resonate long after the last page is read. Overall, Minimum Safe Distance is a compelling sci-fi novel that challenges readers to ponder the complexities of morality and the potential impact of external influences on our future, and I would not hesitate to recommend it to fans of complex and enjoyable science fiction everywhere.


First contact was nothing like we imagined.
Can the aliens save Earth? Should they?

With the Earth teetering on recovery from humanity's 21st century mistakes, two highly advanced aliens observing from the Moon are suddenly on opposite sides of an ethical battle over a dire cosmic threat.

As governments seek to destroy them, the aliens wrestle and scheme, entangling all of humanity as they influence and empower specific humans to achieve their contrary objectives.

Among them are a brilliant AI expert who has channeled her autism in the service of science, and a violent, anti-secular zealot who hates everything she stands for.

Drawn into the conflict, Laurence and Matt must reach minimum safe distance from human nature itself – their own, the rest of humanity’s, and of the former-human, techno-demon ‘monstas’.

Chased into the ruins of the US, they struggle to distill the meaning of personhood, discover the value of their own lives, and in so doing decide the fate of the solar system.

[For the record, MSD was conceived in 2005, completed in 2017, and pro-edited in 2019, then scrubbed several more times afterward. When you read it you’ll see why I mention this. In some ways it was prescient.]

5-star review on TheStoryGraph:
”If you like hard science books, this is for you. Too many scifi books have become "space erotica" or are written/plotted so poorly that you wonder if they're AI generated. This book is a bold attempt to create a world with a truly diverse cast of characters. Written by X. Ho Yen, an autistic writer, it gives an interesting and appealing vision. Enjoyed savoring this book and look forward to future works.” — bitsofbooksness
