How good are the Harry Potter books? So good that many people have drawn maps of Hogwarts based on the descriptions in the book – and they are wonderfully, surprisingly similar. Steve Vander Ark has created a scarily extensive (and I mean, yikes!) website of all-things-Harry Potter (so much so that JK Rowling sued him) with an Atlas of Hogwarts. It shows different peoples' maps of Hogwarts. Check it out, and if you dare, wander over to the other 700 pages of Harryphenalia. Seriously, yikes!
