We'll give you a clue...
Got it?? Any Harry Potter stan would know that Ravenclaw's house mascot isn't actually a raven, it's an eagle. You might remember from the books, Ravenclaw Tower has a bronze eagle-shaped knocker that only lets Hogwarts students through if they can a answer a riddle.
"Our Ravenclaw design has a raven in it," explains Thatcher Wine, Juniper Books' big boss man. "And for the first time I've received complaints that [fans] wanted to see an eagle in it because that's the house mascot."
Luckily, they decided to scrap the original design and print some new, more accurate covers... Phew!!
