I just finished Dust by Elizabeth Bear.

Dust is a very standard science fiction story, the generation ship, updated with more modern ideas like nanotechnology, genetic engineering and distributed artificial intelligence.

Bear adds a touch of fantasy imagery, another approach that has been extensively explored by Gene Wolf in his Book of the Long Sun series.

But even though she is playing an well developed setting, Bear still writes an enjoyable book and, based on this novel, I will check out some of her other works.
