Storm Over Warlock (Forerunner Series #1)

The Throg force struck the Terran survey camp a few minutes after dawn, without warning, and with a deadly precision which argued that the aliens had fully reconnoitered and prepared that attack. A single cowering witness, flattened on a ledge in the heights above, knew that nothing human could possibly be left alive. ~ ~~ ~ Thus, Shann Lantee, most menial of the Terrans attached to that camp, was left alone and weaponless in the strange hostile world. Human prey for the aliens from space. But they were NOT the greatest menace on Warlock!
