This stand-alone novel is widely regarded as Asimov's best science fiction novel. Andrew Harlan is an Eternal, a member of the elite of the future. One of the few who live in Eternity, a location outside of place and time, Harlan's job is to create carefully controlled and enacted Reality Changes. These Changes are small, exactingly calculated shifts in the course of history, made for the benefit of humankind. Though each Change has been made for the greater good, there are also always costs. During one of his assignments, Harlan meets and falls in love with No's Lambert, a woman who lives in real time and space. Then Harlan learns that No's will cease to exist after the next Change, and he risks everything to sneak her into Eternity.
One moment Joseph Schwartz is a happily retired tailor in Chicago, 1949. The next he's a helpless stranger on Earth during the heyday of the first Galactic Empire. Earth, as he soon learns, is a backwater, just a pebble in the sky, despised by all the other 200 million planets of the Empire because its people dare to claim it's the original home of man. And Earth is poor, with great areas of radioactivity ruining much of its soil--so poor that everyone is sentenced to death at the age of sixty. Joseph Schwartz is sixty-two. This is Isaac Asimov's first novel, full of wonders and ideas, the book that launched the novels of the Galactic Empire, culminating in the Foundation series.
