rough-and-tumble planet to ensure that doesn't happen -- even if it
means blowing Lurion to interstellar dust!
In The Plot Against Earth, agent Lloyd Catton must work with
skeptical, suspicious alien agents to bust a hypnojewel racket,
unveiling a multi-planet conspiracy threatening the Earth itself!
In One of Our Asteroids is Missing, independent miner John Storm
discovers an impossible asteroid rich with fabulously valuable metals
and minerals, only to find his claim stolen, along with all computer
records indicating that he had ever existed!

introduction by the author, these three novels of science fiction
adventure blaze back onto the scene, revealing early masterworks of
