Today is the day that JK Rowling releases The Casual Vacancy, marking a break away from the Harry Potter books that made her name. It's a book written for adults without a wizard or wand in sight.
We wish her well with her new venture - for one thing, it means we can read Rowling in public without looking like we're still children inside (which of course we are).
However, for many people, Rowling will forever be the woman who created Harry Potter and encouraged millions of children to read. While her written words have inspired her many, many fans, what she says is often as thought-provoking - much like her memorable creation, Albus Dumbledore.
So much like the wizard headmaster, in fact, that we're not sure your Potter knowledge will be strong enough to tell the two apart. Care to prove use wrong?
