This was written by one of the authors from the issue of Lightspeed that I read recently, and I saw that they’d written something for Tor.com, so of course I had to go find it and read it.1
That said, it was a short story so it’s getting a pretty short review. It’s an interesting concept – you’ve got a loop of universes, each of which contains the next one down, and is contained by the one above. Because it’s all in 11-dimensional space or whatever, the bottom-most universe contains the topmost one, and you get a nice self-contained loop. As it turns out, the way that the universes contain one another is the ‘skunkworks’ – a mass of pipes, ferrying data from place to place, generating the universe it contains. Physics within those skunkworks are rather different, allowing people to do interesting work to tweak the pipes and keep everything working right.
The main character, Ellie, was raised by her mother to be one of those repair workers, and though she’s still new at it she’s already being regarded as one of the best, it would seem.
From that context, it’s a story about family, in a way- you see a couple references to her sister, Chris, who never actually makes an appearance except for temporarily hijacking someone else’s body.2 Mostly it’s about Ellie’s relationship with her mother.
It’s kinda sad, I must say. But, based on the way everyone is described, I think it’s roughly the best-case scenario.
So, trying to avoid any further spoilers here, go have a read, it’s free.
