Now for the first time in trade paperback, this standalone novel introduces a terraforming project gone wrong from a master of biological science fiction.

With Earth overcrowded by its own population, humanity must look to the stars to survive. Advance crews of terraformers explored alien worlds for their potential habitability.

When those terraforming crews introduced the alien Quill to worlds where they did not belong, they saw them only as a mindless form of fungal life. But the Quill multiplied and mutated until they were no longer harmless, making the planets impossible for humans to inhabitants. People waiting for their new homes were instead crowded into space stations in the hopes that a solution could be found. In the ensuing chaos, many stations failed.

For the survivors, their only hope rests in finding a way to wipe out the Quill before the final stations fail.
