These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Crowning Moment of Awesome: Meta example(s): writing a 300-page novel without the most common letter in the alphabet. Also, that all of the translations have the same challenge (so the Spanish translation has no "a").
Dancing Bear: The vast majority of people pick this book up because of the lack of the letter "e", not because of its plot.
