Edmond Hamilton has more published science-fiction stories to his credit than any other author. The Star Kings will be hailed as his greatest work.
The Star Kings is a romance of that great age of space-travel in whose dawn we now stand. As military experimenters send rockets father up from Earth each month, and soberly plan bases on the moon and planets, the shape of a great space-traveling civilization of the future becomes more clearly defined. This story is an adventure into that future civilization – the adventure of a present-day man flung by the sorcery of science across time and space, and into a perilous whirl of intrigue and conflict between the great star-kingdoms of two thousand centuries from now.
This is escapist literature in the finest sense, the most thrilling type of delicious adventure since McCutcheon invented Graustark. Every science-fiction fan, old and new, will acclaim The Star Kings as a classic in its field.
