A gripping, masterfully written adventure set against the violent beauty of a planet in the throes of cataclymic transformation, Against Infinity is Gregory Benford's timeless portrait of a young man's comming 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.
