The planet conceals vital information about the aliens that enslaved the Wiyert--and now threaten Earth. Little time remains to protect humanity. A handful of escaped Wiyert, desperate to rescue their people, offer to guide the team. With their help, Argo's formidable power, and Lea's unique mental abilities, they hope to penetrate Beredul's defenses without detection. They must trek on foot for days across the war-torn surface, pursued by gigantic, nightmare predators to reach the nearest Wiyert stronghold. And comes the hard part.
