Harry Potter and the Chamber of Secrets by J. K. Rowling is the second book in the Harry Potter series. Harry and his friends are back at Hogwarts School for Witchcraft and Wizardry. Most of the students, teachers and other staff we met in the first book, Harry Potter and the Philosopher's Stone are back. The new first year class has at least two Harry Potter fans -- Ginny Weasley and Colin Creevey. We also get to meet a flying car, and Dobby, the house elf. The next book in the series is Harry Potter and the Prisoner of Azkaban.
