When Yellowstone's Super Volcano threatens eruption wiping out the United States, Dr. Thomas Jackson, the world's foremost expert in the geology of aquifers and underground water movements is called upon to lead the frantic effort to reverse the trends hopefully avoiding an eruption. Joined by internationally known disaster response expert, Catherine Craft, who has just finished her rotation leading the massive response to the eruption of Sicily's Mt. Etna and the initial test of her designed and personally-funded revolution in response housing and system. Forged together from two different worlds, Thomas and Catherine encounter personal betrayals and losses as they lead an elite team, uncovering the sinister years' old plot of activating eco-weapons designed to destroy nature and mankind for corporate gain. Despite the huge forces and potential losses in play, Thomas and Catherine immediately connect and navigate unexpected new love as the world closes in on them. They lean on each other as betrayal comes from directions never imagined, from greedy corporations to corrupt government officials to their own twisted families.
