The Bridge to Terabithia novel is number 9 on the 100 Most Challenged Books list. The reason? Because death is part of the plot.
Additionally, one of the characters uses the word "lord" outside prayer, and it's accused that the book promotes secular humanism and New Age religions, occultism, Satanism, and for accusations of sexual content (although there is no sexual content in the book to speak of).
Better add it to the Harry Potter bonfire.
