“The Iron Garden Sutra” by A.D. Sui
Vessel Iris has devoted himself to the Starlit Order, performing funeral rites for the dead across the galaxy, guiding souls back into the Infinite Light. Despite the comfort he wants to believe he brings to the dead, his relationships with his fellow Vessels are distant at best, leaving him reliant on his AI implant for companionship.
The spaceship Counsel of Nicaea has been lost for more than a thousand years. A relic of Earth’s dying past, humanity took the ship to the stars on a multi-generation journey to find another habitable planet yet never reached its destination. Its sudden appearance has attracted a team of academics eager to investigate its archeological history. And Iris has been assigned to bring peace to the crew’s long departed souls.
Carpeted in moss and intertwined with vines, Nicaea is more forest than ship. But Nicaea’s plant life isn’t the only sentience to have survived in the past millennia. Something onboard is stalking the explorers one by one. And Iris with his AI enhancement may be their only hope for survival. . .
Review
This was such a great read! I really loved the worldbuilding and the character developments throughout the book. Iris was such an interesting character to get know along with his AI companion. It’s interesting reading about a character having an AI companion considering what’s going on today but I liked the way the author handled the whole situation. I really liked the way Iris ended up developing various connections and relationships with everyone in the group (especially one character). I really enjoyed the way various histories of the characters ended up being told as they got to know each other.
I thought the balance of character development and solving the actual mystery of the ship was well done. Things happened in a way that necessitated characters talking to each other in a way that made sense. The potential story of that happened on the ship in the past is all too realistic given how generational knowledge is lost over the years. The way everything worked out was also interesting. I did wish for confirmation on one plot, but it’s okay that it was not shown. I also liked the way a specific relationship developed and the way things played out even if the ending felt too abrupt. I did think it made sense given the rest of the story that whatever might happen next was not the focus of the story.
Thank you to NetGalley, Erewhon Books and A.D. Sui for access to the ARC in exchange for an honest review.
