To answer the question in the thread I'm going to shout out for Deathly Hallows. Favourite book and movies. I just think to take Harry out of Hogwarts as a student at least,.a staple of all the books prior and still make the story so gripping and engaging was a real feat. I love the paralysing and claustrophic climate of fear in the book as the wizard community goes to war with Voldemort and his Death Eaters tightening their grip. Muggle born Wizards and witches profiled. The trio on the run and how they fall away and back to each other on the way. And of course Snape's story wraps up very nicely. A great end to a fantastic series.
I totally agree. Especially about the challenge of taking the book out of Hogwarts. Yet it still worked - and so well!
