Brightness Reef

David Brin, the Hugo and Nebula Award-winning author of Sundiver, crafts Brightness Reef, a luminous gem of SF literature. Persecuted refugees from six separate alien races have migrated to the idyllic planet Jijo. And despite their incredible diversity, the inhabitants live together in blissful harmony. However, settlement on Jijo is illegal-and it's only a matter of time before the residents of this forbidden paradise are discovered by the galactic powers-that-be.
