"You were once given a helmet." "A helmet?" The Traveler thought for a long moment. "Yes, Soterion-the defender," he affirmed. "You must learn to wear it in battle," instructed the Preacher. "You take so many blows to your soul because your intellect is open to the enemy." "When am I in battle?" Ishi shook him gently. "Every day is a battle, Traveler! Take every thought captive, remember? Salvation is forever, and yet the need for it occurs in the daily battlefield. You must work it out with reverential fear and trembling. Wear your helmet, Traveler!" Fourth in the Jewels of Earth saga, this novel sends the Traveler careening through human history, searching for the mysterious Omnipoint. He must find it!
