As a novel, not very good: minimal plot, whole chapters devoted to rather tedious lectures on government, finance, etc., etc., blah blah blah.

As the unpublished first novel by Robert A. Heinlein, somewhat more interesting: For Us, the Living is full of scenes, characters and ideas that appear (greatly expanded) in Heinlein's later fiction, so it was amusing to play spot-the-story: The Roads Must Roll, "If This Goes On--", even Lazarus Long's discussion of currency in Time Enough For Love.

For Us, the Living was Robert A. Heinlein's last unpublished fiction. His remaining unpublished works are - I suspect - limited to grocery lists and birthday cards; perhaps we'll be seeing an omnibus edition of them fairly soon....
