All Shook Up: The Life and Death of Elvis Presley is by Barry Denenberg. A look at the life of a rock-n-roll legend that is geared for younger readers. It gives an overview of the life of the "King", but doesn't go into detail that would be inappropriate for younger readers. A way to hook young music fans into reading nonfiction. There is one instance of profanity in a direct quote, but otherwise a clean book.
