This novel was clearly written during or in the aftermath of pandemic lockdown. 5 people are trapped in a literal bubble together, inventing various amusements (including baking projects) to keep themselves & each other occupied. I wish I had done something so productive & impressive! This is the first Chambers novel I’ve read in which there are no human protagonists. As usual, there is a Futurama reference:  Roveg seems sort of based on Dr. Zoidberg, having frills, more than 4 limbs, & an exoskeleton, & always being tempted by free food. I’ve read this whole series kind of wondering “where is the author going with this…”, so the acknowledgements at the end saying that this book is the last book Chambers is writing in this universe makes me more interested in her other books (e.g. the Monk & Robot books) than I was before.
