I just got Kaldar World of Antares in a collection of stories and also Edmond Hamilton’s Return to the Stars the sequel to the Star Kings.
I haven’t read one of his books since i read Star Kings.
Looking forward to reading some of this old pulp Sci-Fi.
Edit:
Kaldar was really bad, it was very poor Burroughs pastiche. The most remarkable things in it are a Star Trek like matter transporter that can move the person to a far away planet, and a Star Wars like lightsaber laser sword.
