Humans return to a long-lost colony. But do they bring enlightenment or destruction to the people who have become natives of Monde D'Isle?
I've been working my way through Liz Williams' books and enjoying them; this is my favorite so far. She creates a beautiful and fascinating world, peopled with interesting and well-drawn people. Ideas are particularly strong in her work, and Ghost Sister, with its genetically modified, wild and tormented not-quite-humans, is no exception. I found the stifling ideology that informs the new human mission to be believable, if fanatical, and quite frightening; I spent the last quarter of the book in terror that I was about to read another That Ancient Light. The characters are sympathetic and vivid, particularly the questioning, idealist Elerres.
Williams is a good sentence-level writer, but at times an overly formal, slightly stiff diction creeps into this particular novel, which lessens its emotional immediacy. Elerres' narration seems particularly prone to this. I would have liked the climax to be a bit bigger and more dramatic, and I wanted to see more of the world -- which in itself is an indication of good worldbuilding, since I got the impression there was more to see. Williams doesn't seem to write in series, but more work set among the Mondhaith would be welcome.
