Harry Potter Book #2

The second book in the series is called Harry Potter and the Chamber of Secrets. Harry has been warned by a small creature named Dobby that Harry must not go back to Hogwarts and that disaster will strike Hogwarts. Dobby was right and disaster did strike Hogwarts. People have turned in to stone and the new professor Gilderoy Lockhart is a real big stuck-up. Who could be causing this mess? Could it be Draco Malfoy? Maybe even Hagrid? Or might it be the biggest of suspects, Harry himself?
