Too little time on your hands?

Try The Guardian's "digested read" of the new Harry Potter and the Half-Blood Prince: Dumbledore appeared at the door. "I've come to take you to the Weasleys," he said kindly. "And when you return to Hogwarts, you will be having some one-to-one tuition with me. You have so much back story to catch up on that you won't be ready for your final adventure unless you do a lot of cramming."
