This seems like a lot to me. Fully .06% of my novel is the word "egg." For reference I should tell you that my novel is in many ways actually about magic, but the words "magic" and "magical" only appear a combined total of 106 times.
For continued reference, I could add that my novel contains 75 mentions of cereal, and this is not accidental. But it also contains a whopping 2,502 instances of the word "and," YET IS NOT ABOUT CONJUNCTIONS.
No doubt some of you have a favorite word and are now wondering how many times it appears in my novel, and whether I could be persuaded to slip it in there if it doesn't. I invite your comments.
