Welcome to Ringworld, an intermediate step between Dyson Spheres and planets. The gravitational force created by a rotation on its axis of 770 miles per second means no need for a roof. Walls 1,000 miles high at each rim will let in the sun and prevent much air from escaping. Larry Niven's novel, Ringworld, is the winner of the 1970 Hugo Award for Best Novel, the 1970 Nebula Award for Best Novel, and the 1972 Ditmars, an Australian award for Best International Science Fiction.

A trusted member of Hitler’s inner circle, Artur Axmann, the head of the Hitler Youth, witnessed the Führer commit suicide in Berlin - but he would not let the Reich die with its leader. Evading capture, and with access to remnants of the regime’s wealth, Axmann had enough followers to reestablish the Nazi party in the very heart of Allied-occupied Germany - and position himself to become dictator of the Fourth Reich. U.S. Army Counter Intelligence Corps Officer Jack Hunter was the perfect undercover operative.

As the Empire reels from its critical defeats at the Battle of Endor, the Rebel Alliance—now a fledgling New Republic—presses its advantage by hunting down the enemy’s scattered forces before they can regroup and retaliate. But above the remote planet Akiva, an ominous show of the enemy’s strength is unfolding. Out on a lone reconnaissance mission, pilot Wedge Antilles watches Imperial Star Destroyers gather like birds of prey circling for a kill, but he’s taken captive before he can report back to the New Republic leaders.
