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 the ship'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 construct may be their only hope for survival. . .

4 stars

AD Sui's previous book The Dragonfly Gambit was quite good, so I was excited to read this next book by them.

The plot hook: Vessel Iris, a monk that specializes in laying to rest those who have died in space, is assigned to a lost generation ship that has suddenly appeared. Surprisingly, there is a team of researchers there already. And then people start dying. Dun dun dunnn.

Unsurprisingly, this book most reminded me of something like Ghost Station by SA Barnes. The part of Ghost Station that I most enjoyed was the ambiguity in the horror elements. What is actually going on? Who can be trusted? Can the narrator even be trusted? In Iron Garden Sutra, there is a little bit of early misdirection, but I didn't believe it for a second and the larger plot arc truth felt clearly foreshadowed. This knowledge caused it to lose …

In Iron Garden Sutra, there is a little bit of early misdirection, but I didn't believe it for a second and the larger plot arc truth felt clearly foreshadowed. This knowledge caused it to lose a lot of tension and weakened the horror side of the story.

What I did really like about this book is how the two major characters have slowly revealed backstory and trauma that intertwines with each other and the greater plot going on. It's also got a similar enemies-to-lovers vibe that was in the previous AD Sui book, and the strength of this one too is absolutely in the characters and their relationships.

It is (apparently?) the first book in a series, so I'm quite curious where it will go from here in terms of plot and genre. There's a lot of space (:drum:) for any number of story directions.
