A storm rages over the north of Britain and a troop carrier founders in the Irish Sea. Flood indicators are off the scale, the seas are mountainous, and a spring tide is about to strike the east coast. Air sea rescue and military personnel struggle to save lives but the worst is yet to come. When the storm reaches the south, the two forces of wind and tide will combine to send an enormous, one-in-a-thousand tidal surge up the Thames. When an oil supertanker explodes in the estuary, it ignites the river, sending a wall of fire and water towards Britain’s capital. This devastating and compulsive thriller is the story of what happens next, and the desperate attempts to save the capital from destruction.
