A reader asked for suggestions. I said I would ask for your ideas:

My sister is an experienced teacher struggling to keep her chin up in an impoverished district serving children whose parents are non-English speaking or meth addicts. She and her staff want to form a book study group this year – looking for ways to enhance their professional practice and their children’s lives – wanting desperately to have positive and productive conversations about this important work during these bleak times. Can you or any of your “followers” recommend some titles for them to consider? A retired teacher myself, I remain passionate about helping those who carry on.
Thank you for any and all suggestions.
