I’d place this book (novella, really) in between those two. I didn’t dislike it like Spiderlight, but I didn’t love it like Elder Race. It’s another story of a (in this case, literal) group of outsiders and how they react to their situation. Like the other two books, the characters aren’t especially likeable but at least in this case I actually still cared about the main one enough to continue reading.
Overall it was fine, but with a win, a loss, and a meh, I’m not feeling a strong desire to pick up another Tchaikovsky book for a while.
