A Harry Potter Adventure

"Amazing!," you exclaim to yourself. Hagrid has sent you a gift you can actually use. It's a journal and the engraving on the cover reads "Harry Potter". This is so cool! Your very own journal to record your own thoughts and feelings. Might be good for jotting down some spells too! But there's no note. You search through the wrapping, but find nothing. As you open the leatherbound book, you see that Hagrid has written his greeting on the inside of the cover.

"Dear Harry,
Happy Birthday. I saw this journal one day in a store as I was shopping through Knockturn Alley and thought you might like it. I know it's not much. The shopkeeper says it's supposed to be a magic journal, though I can't figure out what's so magic about it. I thought I'd leave that part up to you. As you know, I've never been extremely good at figurin' stuff out. Dumbledore will be sending Dobby to your house early Saturday morning to take you to Diagon Alley. Nothing has been heard of "You-know-who" since you last saw him. It worries Dumbledore and whatever worries Dumbledore, worries me. If you need to reach me, it's best to wait untill you get to Hogwarts. You never know who might be intercepting messages sent through the owl post. Meet me around the back of my hut once you arrive. Take care of yourself Harry. See you soon,
Hagrid"

Hagrid said he purchased the journal at Knockturn Alley which worries you very much. Knockturn Alley is the shadiest place you have ever been to. Nothing good could come out of there. What was he doing there anyway? Why shouldn't you send letters by owl post? Is Voldemort looking for you right now? You can't wait to tell Ron and Hermione about Hagrids warning.
