When the ice begins to breathe, the world begins to drown. Dr. Emma Marcus sees it first-the numbers that shouldn't exist. Greenland's glaciers are collapsing faster than physics can explain, and the shifting mass of meltwater is altering the planet itself. Her warning to world leaders is ignored, dismissed as alarmist fiction. But deep beneath Yellowstone, the Earth is already responding. Across the globe, the signs converge. In Yellowstone, seismologist Jamie Sato detects a pressure surge that defies geological history. In Nigeria, climatologist Lima Okonakwa watches the jet streams unravel into chaos. And in America's heartland, Army engineer Major Mike Harmon faces the impossible task of holding back an ocean that no longer recognizes its boundaries. As sea levels climb and weather systems merge into monsters, science becomes survival and data becomes prophecy. Humanity's final days unfold not in fire, but in water-an extinction-level event born from its own arrogance. From the glaciers of Antarctica to the flooded plains of the Midwest, High Tide is a breathtaking, hard-science thriller of global collapse and human resilience. It is a warning, a requiem, and a testament to the few who refused to look away. "We have done the science. Now we perform the last experiment- to see if a whisper can outlast a scream."
