Debris by Jo Anderton passed the test quite well. Anderton has an enjoyable authorial voice, a welcome relief in a genre with too many plodders. Her plot, while probably spread a little thin for 450 pages of novel, nevertheless takes the reader through a fascinating world that has amazing technology (pions, little lights that build, fix and heal) but that has mostly forgotten how it all works.
Much like Daniel Abraham's Long Price Quartet, Anderton creates her own wonderfully original fantastic world. I have no idea if this is fantasy or science fiction and I don't much care. It's so nice to see contemporary authors using the genre's freedom to build really cool things -- and being rewarded with publication.
