I have not read either book, but I noticed the recommended reading age is 16+, not little kids . The other book, All Boys Aren’t Blue is also not appropriate for kids under 16,and states it is for 14-16.
This article makes a good point in that if they were movies,
they would be rated R and those under 17 would require a parent. I would agree they should not be in a school library (and certainly would not have been when I was school aged).
But what the other banned books such as the ones I mentioned?
