Serialized in Amazing Science Fiction Magazine in 1972, published as a novel in 1975. The Jovian Astronautical-Biological Orbital Laboratory, a.k.a. "the Can", is the only home 17-year-old Matt Bohles has ever known. Concerned about the aging space station's failure to find evidence of alien life on Jupiter or its moon, the cost-conscious powers back home have determined that all non-essential personnel must be evacuated. Now, unless Matt can somehow prove himself to be an invaluable member of the scientific team, he faces exile to a dangerous, frightening, and unfamiliar place: Earth.

A gripping, masterfully written adventure set against the violent beauty of a planet in the throes of cataclysmic transformation, Against Infinity is Gregory Benford's timeless portrait of a young man's coming of age. On the poisonous, icy surface of Ganymede, a man and a boy are on a deadly hunt. Their prey is the Aleph— an unknowable alien artifact that roamed and ruled Ganymede for countless millennia. Indescribable, infinitely dangerous, the Aleph haunts men's dreams and destroys all efforts to terraform Ganymede into a habitable planet. Now in a modern world ancient struggle is joined, as a boy seeks manhood, a man seeks enlightenment, and a society seeks the power to rule the universe.
