Book Description: This World is Not Yours by USA Today bestseller Kemi Ashing-Giwa is the perfect blend of S.A. Barnes’ space horror and Cassandra Khaw’s beautiful but macabre worlds. An action-packed, inventive novella about a toxic polycule consumed by jealousy and their attempts to survive on a hostile planet.
After fleeing her controlling and murderous family with her fiancée Vinh, Amara embarks on a colonization project, New Belaforme, along with her childhood friend, Jesse. The planet, beautiful and lethal, produces the Gray, a “self-cleaning” mechanism that New Belaforme’s scientists are certain only attacks invasive organisms, consuming them. Humans have been careful to do nothing to call attention to themselves until a rival colony wakes the Gray.
As Amara, Vinh, and Jesse work to carve out a new life together, each is haunted by past betrayals that surface, expounded by the need to survive the rival colony and the planet itself.
There’s more than one way to be eaten alive.
Review: Thank you to NetGalley for providing me with an eARC of this novella!
When “This World Is Not Yours” by Kemi Ashing-Giwa ended up in my inbox, the cover alone caught my attention. I mean dang, look at that cover. The expression on that person’s face! And looking more into the story itself, I was absolutely intrigued by the premise of a space colony with a strange ecosystem, and a ‘toxic polycule’ (we all know that I LOVE that kind of drama). And the phrase ‘There’s more than one way to be eaten alive’? GIVE IT TO ME NOW. Suffice to say, I was going into this novella with some high hopes.
First the highlights. I am always game for a sci-fi/space horror tale that brings up some of the perils of colonialism, especially on an unfamiliar planet with an unfamiliar ecosystem and with mechanisms that aren’t fully understood. This is one of the reasons I loved “Annihilation”, and the Gray and New Belaforme colony really reminded me of that novel in a number of ways. Secondly, the space horror in this book is unrelenting, it builds some good tension, and when the tension breaks it is GORY AS HELL and in the best and most horrifying ways possible. First with the tension bit. There was one moment where someone was literally swimming in The Gray and I am pretty sure I clamped my hand over my mouth because I knew that could NOT be a good idea, but Ashing-Giwa takes her sweet time in pulling out all she can from the suspense. And then when we do finally get a pay off for it, and the tension breaks into a gory, terrifying mess?

All of this was spot on.
That being said, and this is in a lot of ways a ‘me’ issue, I wasn’t as enthralled with the Science Fiction stuff. I am at the point where I need to just tell myself ‘look Kate, even if it’s Space Horror, Sci-Fi isn’t your thing’ and maybe not take it on. And in “This World Is Not Yours” we get a lot of that, with colonies, space intrigue, Science Fiction scenarios involving populations and ecology, and lots of references to tech that kind of made me skim the pages a bit. I will reiterate that these are all things that are to be expected in this genre, and people who like that will probably like how it is done in this. So that negative aspect is probably on me. But along with that I didn’t feel like I really got to know our characters as much as I would have liked, especially Jesse, one of the cornerstones of the polycule that has been forced upon our main characters. I understood his connection to Amara, but the connection to Vinh was more talked about than really demonstrated. I think to buy some of the high stakes moments at the end I needed more from Jesse. I also needed more development of Vinh’s assigned husband Henry, because Amara REALLY hates him and I understood why she would hate him as a jealous wife, but he seemed pretty bland until there were a couple of hail Mary moments of terribleness that felt like they were there to be like SEE THIS IS WHY YOU SHOULD HATE HIM that didn’t feel super earned. On top of that, Amara and Vinh as the couple we are supposed to be rooting for didn’t really click with me. But this could have been solved had we explored them more, and I think that we probably needed more pages to do so.
So all in all “This World Is Not Yours” was a bit mixed for me. The space horror at its peak was fantastic. But it wasn’t as centered as I had hoped it would be.
Rating 6: When the space horror was in full force it was terrifying. But a lack of character development and a little too much Sci-Fi made this not the home run I had hoped for.
Reader’s Advisory:
“This World Is Not Yours” is included on the Goodreads list “Queer Polyamory”.
