Bonus post for the last day! This one isn’t on the ALA list that I saw, but it has been banned, and it’s a favorite of mine.
Stranger in a Strange Land; Robert Heinlein
The main character is a human raised on Mars, by Martians. He goes back to Earth, but experiences all sorts of ‘translation’ issues, because despite his biology, he’s a Martian, but everyone persists on treating him as if he were like everyone else. Heinlein explores what makes you human, religion and religious intolerance, and how to achieve happiness in life.
Once again you have to have a sense of humor about how religion is approached, and there’s some frank sexuality that might bother some people. But all in all, it’s fairly innocent–and definitely insightful.
“The worst that can possibly have happened to him is death and that we are all in for—if not this morning, then in days, or weeks, or years at most.” – Robert Heinlein
