Jotun reinforcements were charging up as I opened the jets wide and blasted off. The plane soared into the freezing air, and I was glad I had taken time to don my flying clothes and oxygen tank. Even through my wired suit, I could feel the numbing chill, and my lungs were laboring under the lessened pressure.

Far below, I saw the glimmering river through the closing mist. The tall masts of Jotun ships looked like dowels. I twisted the firing wheel to top speed, and we rose so steeply that I thought the ship would slip into a tailspin. But it righted and zoomed higher, rocketing above the misty river and the dark, fog-shrouded forests beyond. When I looked back, the ominous citadel of Jotunheim was alive with moving torches. I could well imagine the blazing anger that Loki would vent upon the Jotuns because of our escape.

"We're clear!" I thought exultantly. "Maybe by now Loki has more respect for outland science."

I set the robot controls and searched through the spare-parts compartment for a new window. Fixing the smashed port was only a few moments' work. Then I opened the oxygen nozzles wide and let the cabin fill with fresh, invigorating air and warmth. I removed my flying togs and opened the freight hold door. Freya and I helped Frey into the cabin, put him in a seat. His blurred eyes looked less helpless, and he sat unsteadily but without collapsing.

"Are you all right?" I asked anxiously.

He nodded weakly.

"Truly you outlanders have strange powers," he mumbled. "We must warn Odin of the attack…"

"Loki means to use those devilish storm-cones to overcome the Aesir," I said. "We've got to devise some defense against that weapon."

I went back to the controls and guided the plane above Midgard's black hills. Freya's frantic voice called to me over the roar of the rocket motor.

"Jarl Keith, Frey has fallen!"
