Mark Twain 
Adventures of Tom Sawyer [PDF ebook] 

The orphan Tom Sawyer, raised by his aunt, is never out of trouble for long. A mischievous, charming boy (not to mention genius at escaping from trouble), Tom’s adventures involve many unwitting bystanders. From one moment to the next, the boy could change into a pirate, or ship’s captain — when he’s not trying to win Becky Thatcher for a sweetheart, of course. Tom is also a friend of Twain’s other beloved boy-hero, Huckleberry Finn.
