How this generation will communicate meaning will be a problem.
I don’t think you’ve read much young adult literature recently, if that is your opinion. The YA genre is flooded with wonderfully engaging characters and story lines. Give some of them a try before condemning them. Harry Potter, The Hunger Games, the Divergent series, these are all very engaging books for older elementary and junior high kids. Now, what none of these books do is try to inculcate the Judeo-Christian mores and ethics, or the American story that we were taught, but they all certainly speak to big themes like courage, curiosity, and character. I would love to see some author take the imagination and fast pace of The Hunger Games and tie it in with an American/Christian perspective, but I haven’t found anyone who has been able to do that well.
