The Alex Cave Adventure Wagon is rolling again in Cold Energy. Geology instructor Alex Cave and his best friend Okana must solve the mystery of the sudden freezing temperatures and the awakening of a sleeping volcano in the Pacific Northwest. Join their journey from the Puget Sound to the Aleutian Islands and the Bering Sea, with a quick stop at Area 51. Alex receives the urgent message from a friend in Northern Canada. The polar ice sheet is mysteriously expanding by thousands of square miles in a matter of minutes. He begins a desperate race to find the cause, and joins the crew on board the high-tech research ship Mystic, but Captain Dieter has other plans for the stealthy craft and changes course to an unknown island in the Bering Sea. Dieter expects to find a horde of treasure stashed by the Nazis near the end of WWII, but what Alex discovers is even more incredible than he could ever imagine. The ice sheet continues expanding at an alarming rate, trapping anything in its path. It will cover the planet in a matter of days, unless Alex and Okana can find a way to stop the world from entering a new ice age. He also discovers a 180-million-year old alien artifact of incredible power, but before he can take it to a safe location, Rita Harrow steals the device and kidnaps another good friend, thinking he knows how to operate the artifact. Alex knows if their experiment goes wrong, they could start a chain of events that could lead to the demise of our civilization. And if that wasn't enough, his past actions while working for the CIA have come back to haunt him and his loved ones are put in grave danger by his old nemesis. His enemy's quest for revenge could not have come at a worse time, because he only has a few hours to find the artifact and shut it down. If he fails, the device will cause a super volcanic eruption and no living thing will survive. On this emotional roller coaster, Alex feels the weight of the world on his shoulders as he is torn between saving his loved ones, or saving humanity from extinction. Can he find a way to save both?
