Having moved from swords-and-sorcery to straight sf, Lancour goes to considerable--though not always productive--pains to construct the planet Llarum and its economy and inhabitants. And Llarum is the latest stop for Cort Devereaux, a planet-hopping flamegun for hire. Work is scarce on Llarum, but finally Cort is approached by an old man full of anti-aging drugs who hires him to help the independents who are fighting the Company, the economic mainstay of Llarum. Both sides of this battle collect globes--brainless bioluminescent creatures that graze in Llarum's planet-girdling caves, never see sunlight, and are reduced to luminescent powder by the Company (it uses ""everything but the sound"" in recycling globe chemicals). So Cort becomes an underground shepherd, herding the gorgeous globes while they graze and going out to collect wild globes to add vigor to the stock. But then he's attacked by the mercenary Tremani (the same soulless giant thugs who destroyed Cort's home planet)--and in fighting them, Cort discovers that his boss is also the chief stockholder in the Company! Bland, old-fashioned action-sf, not for the scientifically or philosophically adventurous.
