Reviews

"His most effective piece of work. Asimov's exemplary clarity in plotting is precisely suited to the material at hand." --Locus "By literary standards, this tale of time travel from the 95th century is generally rated Asimov's best." --Entertainment Weekly "Asimov's flirtation with the tropes employed by A.E. van Vogt and Charles Harness is startling for an author deemed ultra-rational and scientific....The effects of this influential, seminal book echo to the present, in the works of such writers as Greg Egan, John Varley, Kage Baker, and Greg Bear." --SciFi.com
