LEGO Harry Potter books
There's been a slew of new LEGO Harry Potter books released this week, the best of which is this Building the Magical World book which includes an exclusive Harry Potter minfig.
There is also not one but three sticker books, which are like the Star Wars and minifigure ones that were released last year. I received mine last week and two of them appear to be a subset of the third, the 'Ultimate sticker collection'.
My Building the Magical World is currently in the post so I'll write a review as soon as I have it.
