Need something new for your reading list? This week, we recommend A.D. Sui’s The Iron Garden Sutra, a meditative horror sci-fi/fantasy and murder mystery.

I don’t typically gravitate toward locked room mysteries, but the description of this book ticked all the right boxes to win me over: “a death monk and a team of researchers trapped onboard a spaceship of the dead encounter something beyond human understanding.” It has all the makings of a compelling murder mystery, which is fine on its own, but thanks to the philosophical musings of its main character, Vessel Iris, and a setting that almost demands existential contemplation, it becomes something much deeper.

Vessel Iris is a monk some time in the far future whose mission is to perform funeral rites for the dead so their souls may reach their ultimate destination, according to the beliefs of his religion, the Starlit Order. “Vessels” like Iris share their mind with an AI companion, which creates a really interesting dynamic for the reader, as there is a constant dialogue going on between the two from the start (carrying a tone that sometimes verges on “old married couple,” which I quite enjoyed). Iris shows up to an ancient ship called the Counsel of Nicaea expecting to perform his duties for the long-deceased on board and instead finds himself facing a group of researchers who are very much not dead — and a jumbled mess of bones from the hundreds of bodies they disturbed by moving, which he’ll have to sort in order to properly bless.

Despite being a ghost ship in most respects, it turns out the Nicaea is alive with vegetation and gardens that would have once supported the humans that lived there. And, there’s seemingly something else, as Iris’ AI begins to pick up strange pings from a presence on the ship, and one by one the team of researchers starts getting picked off. As everything unravels, Iris begins to question his faith and his purpose.

This was such a great read, and I was excited to learn it’s the first in a two-book series, The Cosmic Wheel series. Fans of horror sci-fi/sci-fantasy should definitely check this one out.
