Compelling science fiction adventure from New York Times bestseller Robert A. Heinlein: two classic novellas and two short stories with speculation on what makes us human.

Gulf: in which the greatest superspy of them all is revealed as the leader of a league of supermen and women who can't decide on quite what to do with the rest of us. The prequel to Heinlein's later New York Times best seller, Friday.

Lost Legacy: in which it is proved that we are all members of that league of the superhuman–or would be, if we but had eyes to see.

Plus two great short stories: Two of the master's finest: one on the nature of being, the other on what it means to be a Man. The second story, "Jerry Was a Man," was adapted for the TV series Masters of Science Fiction, and is now available on DVD.
