Skyripper. Soviet Union physicist Emil Vlasov concludes that aliens will attack the aliens. He knows his country cannot defeat the enemy, but the Americans with his help could if he can persuade them of his contention. Espionage agent Tom Kelly receives the information, vowing to insure the outer space invaders are defeated though he leaves dead anyone trying to prevent his achieving the objective in a timely manner.
Fortress. In 1965 President Kennedy builds construction of the Fortress space station to prevent major wars especially nuclear from happening and to thwart hostile aliens from space. In Turkey, an alien corpse is found; coupled with evidence from the Soviet Union has espionage agent Tom Kelly fearing the space station may start WWIII while he also believes alien invaders are coming.
The reprint of two late 1980s over the top of Olympus Mons Tom Kelly science fiction thrillers contains more blood than a bank and somewhat feels its age. Still these James Bond vs. aliens and Communists thrillers are fun to read.
