The moment I saw Harry Potter, I clicked it in an instant . But to go straight directly to the point, my most fave book in the Harry Potter series is the Harry Potter and the Deathly Hallows. It is tragic , yes , but I love how the story flows and it's ending - IT IS JUST SO DRAMATIC AND AWESOME! I LOVE HOW THE STORY SHOWS THAT EVERY ENDING IS A NEW BEGINNING. SO MUCH LOVE .
