1956 Best Novel Hugo

The 1956 Best Novel Hugo was presented September 3 at NyCon II. This third year of the Hugos there was for the first time a shortlist of nominees, with the winner selected by voting by the members of the convention.

Winner: Double Star by Robert A. Heinlein (Astounding Feb,Mar,Apr 1956)
(Some categories were close enough in the mail ballot to require additional voting at the convention; Best Novel was not one of these, and Double Star won decisively.)

Runners-up (not in any order):
