When Princess Harriet Hamsterbone was born, her royal parents naturally didn't invite the evil fairy, and so of course the evil fairy cursed her to prick herself on a hamster wheel on her twelfth birthday and die; and of course the three good fairies softened the curse -- and that's where things get really funny in Ursula Vernon's 2015 middle-grades fantasy Hamster Princess: Harriet the Invincible, the first in a wildly successful series.
