En snabb google föreslår att detta är " Legionens slav ", tredje delen av trilogins soldat av legionen.
The O's had killed two billion humans. Beta Three wanted revenge. The Mound was in his sights.
"There's no way the O's are going to inherit this world. It's going to glow in the dark first." When squad Beta is sent on a recon mission to Uldo in the Gassies, they find the Omni's--deadly aliens with unstoppable psychic power loose in the wrong universe. In a snowy landscape they discover the Mound, a massive, mysterious structure built by the O's. Approaching, they find the way lined with the impaled bodies of innocent humans.
