No kids books have been listed, but I have found them all too often enlightening. Sometimes even more than an adult book.
I and my kids have enjoyed all of Graeme Base's books, but The Eleventh Hour is particularly good and have given it to many kids and adults: http://graemebase.com/book/the-eleventh-hour/
I am also thinking about giving Yertle the Turtle By Dr. Seuss out to anyone I meet before the election: https://en.wikipedia.org/wiki/Yertle_the_Turtle_and_Other_St... I have given many Dr. Seuss books away as well.
