After graduating from Oakstown High School, Trevor Van Pelt, along with his girlfriend Karen Dickson, and his friends John Crenshaw and Suzy Moore all go to the beach for beach week. Then all of a sudden, while at the beach, Trevor has a premonition of a tragic tsunami that washes away and kills everyone who was on that beach. Because of his premonition, he manages to save a bunch of people from their pending doom. Later on in the book, after the memorial, everyone that was in Trevor's premonition start to die off one by one in the order they would have died in his premonition. He tries to tell the people that are next about it, but they don't listen to him and they react badly about it; they eventually die. Death does this through the whole book until everyone is gone. Is there a way to stop his sinister plans? You will have to find out.
