Something is going badly wrong for boys. Rates of depression and self-harm are climbing. Boys are drifting online in search of education and identity, while falling behind in school; absorbing lessons on masculinity and manhood from algorithms rather than adults. The messaging they receive tells them to be louder, tougher, more extreme - while the world around them needs men who can be calm, kind and emotionally fluent. Fathers know their sons are in trouble, but how do we start putting it right? Twelve Rules For Raising Boys explores the cultural, biological and digital forces shaping boyhood today, from what it means to be a man, to navigating the digital landscape and teaching emotional strength. Each rule is grounded in expert insights spanning neuroscience, psychology, social media, masculinity studies and youth development. Revolving around understanding, connection and laying the foundations for a strong future, this is honest, expert-led guidance for men who want to do better by the boys they love. Rob Kemp has a young adult son, and the perspective that comes from two decades of fatherhood. Joe Warner has a four year-old, raised in a world of screens, influencers and AI-shaped manhood. Together they bridge generations - one with wisdom, the other with an urgent call to action - to give today's fathers the tools, language and confidence they need to raise good men in the making.
