From Back Cover:
Everyone knew that David was a smart one. He could tell you the end of a story from the first sentence. The other kids wouldn't even go to the movies with him anymore; he always spoiled the surprise ending. People were beginning to wonder about David. There is, after all, such a thing as being too smart for your own good. David had learned the hard way to keep his thoughts to himself. Even though he was always right. Always. But now David was growing up. And his gift was turning into a power. The power to read people's minds. To see the future. To know things - terrifying things - that he didn't want to know. Like who would live. And who would die.
