Within moments, saying nothing, moving the swift, silent movements of desperation, they had freed themselves of the grasping snare of the jungle beneath them; were once more strong, liberated things in the vast freedom of Space.

"And now Ihelos!" Kriijorl cried as they broke swiftly from the ecliptic of the great spangled ring of Thrayx. "If we can but escape their fleet. Any moment they should be on the scanner, forming to meet the onslaught of Ihelian squadrons—"

"No!" Mason said, and his voice was like a solid thing clogging his throat. "No, not Ihelos—not yet!" His eyes burned, and the red welts that covered his body had begun to sting, to pain, and it was hard to think.
