Flux — Stephen Baxter

Imagine a race of submicroscopic humans, genetically engineered to live in the universe's most hostile environment, the turbulent superfluid mantle of a neutron star

Imagine that the memory of the superbeings who created them has been kept alive from generation to generation.

Now imagine the most incredible family reunion in history--and you're ready for the latest mind-expanding adventure from the dazzling new master of Hard SF.
