The river of time.

The River of Time brings together eleven of David Brin's finest shorter works, including 'The Crystal Spheres', and four stories published for the first time in this collection, each with an afterword by the author.

Powerful tales of heroism, playful excursions into realms of fancy, and profound meditations on time, memory and man's place in the universe show the range and richness of one of science fiction's most imaginative and exciting writers.
