Here's the next book to celebrate your freedom to read with! Andy Riley's The Book of Bunny Suicides believe it or not, was challenged at a high school this year because "it's wrong" Essentially, the complaint's argument was that suicide was not something to laugh at or even "for school age children" according to quotes in news articles.
Luckily the book was returned to the bookshelves after a decision by the school board.
The Book of Bunny Suicides is a humor publication with one panel comics of bunnies trying various hysterical ways of committing suicide. The cover is a good example of its humor.
