Grandma VS Doomsday

When the sea vanishes beyond the horizon, the townspeople rush onto the exposed seabed for its stranded riches. Only the stubborn grandmother Ruth recognizes the warning. No one believes her—until Tucker, the grandson she loves most, is swept into a nightmare of giant crabs, sea serpents, and catastrophic floods. Their only hope may be an ark controlled by the ruthless Captain Brunner, but fear, lies, and dwindling resources soon prove more dangerous than the creatures themselves. As an enormous shadow awakens beneath the water, can Ruth lead her family to the last high ground—and what must be saved first: their lives, or their humanity?
