I really enjoyed this book, but I don't think my review can sum it up better than this conclusory paragraph from the last chapter:
"In the end we need to develop a new model of masculinity. Young men must understand on a deep level that being a real man isn't going along with what you know in your heart to be cruel, inhumane, stupid, humiliating, and dangerous. Being a real man means doing the right thing, standing up to immorality and injustice when you see it, and expressing compassion, not contempt, for those who are less fortunate. In other words, it's about being courageous."
Most of us know there is something weird about today's pre-adult gender roles, played out in Guyland, and perhaps by understanding this terrain we can adjust our cultures to reduce the negative aspects of those strange years.
I can think of few people who wouldn't benefit from this book, and I highly recommend it.
