The Lightning Warrior

In The Lightning Warrior, a giant named Cobalt comes to town to capture the infamous white wolf as an accompanying present for his proposal to Sylvia Baird. Excerpt: "From Dawson to the Bering Sea, Cobalt had no other name. The flame of his hair never won him the nickname of "Red" or "Brick." He was only Cobalt from the beginning to the end, and this name, no doubt, was given to him by his eyes, which varied according to his temper from a dull-steel gray to an intense blue with fire behind it."
