Despite a mind breaking premise that I had to double back on because it got confusing, I loved this, well, novel novel. But first the plot:
Laurel Salter is a mycologist, currently living at the McMurdo base in Antarctica, working as a steward. Like most of the crew there, she is fleeing life on the mainland or at least trying to move on from her problems. However, everything changes when The Arc shows up over the ice, a shifting dome of aurora lights that don't exist anywhere else on Earth. Laurel starts dreaming of The Arc, and her life becomes even more precarious when her ex-husband Eli comes to document the anomaly. Laurel begins to believe that The Arc is a gateway into the universe that Eli has spent half his life studying, the mirror to our own where time runs backward (for example; a collector's antique artifacts in 2019 are floating beds and hi tech windows that barely work). Laurel will stop at nothing to get to this universe, to correct a mistake that took the life of someone they both treasured.
I simultaneously loved and hated the worldbuilding of this novel. The concept of a mirror universe where time runs backwards is actually quite unique. However, in the second half of the novel, when Laurel and Eli were in this mirror universe, I was sometimes very confused. The dates go backwards, and doing the mental math to figure things out like ages was hard; in addition to this, the conceit of what birth and death are in this mirror universe where genuinely hard to grasp until deep into the last act of the book (both are genuinely horrifying). I also like that Laurel tried to live in this new universe fully, and didn't treat it as her own personal trial. (The science was interesting to me too, and felt relatively plausible, and I appreciated the detailed explanations.)
The themes' exploration of grief and motherhood that began the book was also powerful to me. Laurel has very clearly stopped coping with her grief and has pinned her hopes on this other universe, and you can see that in the way she interacts with the people at McMurdo and Eli, when he comes to the base. I think that this feeling of grief really anchors the flashbacks we experience, and acts as a sufficient through line to keep readers from getting lost. However, some readers might find the flashbacks confusing which is completely understandable; the book is in third person limited which ads to the initial mystery and keeps a distance between characters, but can make time jumps jarring. (Be warned as well, that child death happens, it is a very heavy topic, so proceed at your own risk.)
The prose was vivid and rich and extremely detailed, which might be seen by some as unnecessary, but was another thing I really enjoyed. However, again, this can bloat the book for some readers which is understandable, it is a book that invites you to see the leaves for the trees so to speak. However, this may lead to some losing the plot.
The characters themselves were serviceable, if a bit thin. Except our two main leads, we don't spend a ton of time with them. They seem nice, but I frequently had to page back to remember who they were. I did appreciate the incidental LGBTQ rep however. I love Laurel and Eli though, two broken people trying to mend each other after a terrible tragedy. They are written in a way that feels raw to me, and I was rooting for them both at the end. There are a few scenes of them romantically involved with each other, but this is not a romance, and the scenes are easily skippable if needed. However, they are explicit. I found them to be fine as an Ace person, although not my cup of tea.
If you can wrap your mind around the premise, and stomach some very heady prose, you'll enjoy this book.
Thanks to NetGalley and the publisher for the ARC!
