This trio of novels that explore what it means to be human centers around an alternate bioengineered "superhuman" race on Earth called the Ler and their intricate civilizations throughout the galaxy.

Out of print since 1985, these three classic novels form a trilogy that chronicles the history of an alternate human race, the Ler, from their origins as a bioengineered "superhuman" race on Earth to their complex civilizations in space. Together, the books form a challenging examination of what it means to be human.

What's the best way to create artificial intelligence? In 1950, Alan Turing wrote, "Many people think that a very abstract activity, like the playing of chess, would be best. It can also be maintained that it is best to provide the machine with the best sense organs that money can buy, and then teach it to understand and speak English. This process could follow the normal teaching of a child. Things would be pointed out and named, etc. Again I do not know what the right answer is, but I think both approaches should be tried." The first approach has been tried many times in both science fiction and reality. In this new novella, at over 30,000 words, his longest work to date, Ted Chiang offers a detailed imagining of how the second approach might work within the contemporary landscape of startup companies, massively-multiplayer online gaming, and open-source software. It's a story of two people and the artificial intelligences they helped create, following them for more than a decade as they deal with the upgrades and obsolescence that are inevitable in the world of software. At the same time, it's an examination of the difference between processing power and intelligence, and of what it means to have a real relationship with an artificial entity.

Engaged, passionate, and consistently entertaining, An Informal History of the Hugos is a book about the renowned science fiction award for the many who enjoyed Jo Walton's previous collection of writing from Tor.com, the Locus Award-winning What Makes This Book So Great. The Hugo Awards, named after pioneer science-fiction publisher Hugo Gernsback, and voted on by members of the World Science Fiction Society, have been presented since 1953. They are widely considered the most prestigious awards in science fiction. Between 2010 and 2013, Jo Walton wrote a series of posts for Tor.com, surveying the Hugo finalists and winners from the award's inception up to the year 2000. Her contention was that each year's full set of finalists generally tells a meaningful story about the state of science fiction at that time. Walton's cheerfully opinionated and vastly well-informed posts provoked valuable conversation among the field's historians. Now these posts, lightly revised, have been gathered into this book, along with a small selection of the comments posted by SF luminaries such as Rich Horton, Gardner Dozois, and David G. Hartwell. "A remarkable guided tour through the field—a kind of nonfiction companion to Among Others. It's very good. It's great."—New York Times bestselling author Cory Doctorow, Boing Boing on What Makes This Book So Great At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.
