The Solar Invasion
(Captain Future #20}
by Manly Wade Wellman (1946)

It comes from beyond the fifth dimension–an alien intelligence both invulnerable and totally evil. Its aim: bring the universe to its knees. Its primary objective: destroy the Solar System. As doomsday rushes ever closer, one lone man dares oppose the creature from beyond. Only he can save the universe from a brutal, blazing cataclysm.
Another author takes on Edmond Hamilton’s Hero. Just one story, and that’s a good thing. It has all the breathless excitement of the others, but just isn’t as good.
The moon is stolen. That’s right, just taken. Never mind the tides, it’s disappeared into dimension X. And that about sums up the amount of scientific thought that has gone into this story. There is a lot of science hand waving and avoidance. And at the end there is a big incomprehensible space battle. Fortunately it’s short at 40k words.
