"One of the most impressive bodies of work in contemporary science fiction . . .The Chronoliths stands with his best." — The New York Times

One day in Thailand, 21st-century slacker Scott Warden witnesses an impossible event: the violent appearance of a 200-foot stone pillar. Its arrival collapses trees for a quarter mile around its base. It appears to be composed of an exotic form of matter. And the inscription chiseled into it commemorates a military victory . . .sixteen years in the future.

As more pillars arrive all over the world, all apparently from our own near future, a strange loop of causality keeps drawing Scott into the central mystery—and a final battle with the future.

The Chronoliths is a 2002 Hugo Award Nominee for Best Novel and the winner of the 2002 John W. Campbell Memorial Award.

"Superb." — Publishers Weekly (Starred Review)
