Censorship is an inherently political topic. Talking about the book and why we think it should be read is political. But, okay.
How to Eat Fried Worms by Thomas Rockwell first published in 1973... It's not a great book, the only reason I have any memory of it is because of the title and the fact that it was one of the first books I chose to read, but it's amazing that something so bland an innocuous might be banned/challenged.
My grade-school teacher read that book aloud to us. I have no further memories about the book.
