The nation's favourite doctor, Dr Ranj, is here to explain everything you ever wanted to know about puberty - plus lots more.

What does it mean to be a boy? And I'm not just talking about what you have between your legs, but what life is really like for boys. Growing up is a real minefield! So I've put everything I've learned both from my career as an NHS doctor and my own life experiences into this twenty-first century guide to being a boy.

It covers the obvious things like the physical changes you'll go through during puberty and adolescence (hello, pubic hair and voice breaking!), but also helps you to figure out how to manage your emotions, deal with friends and family and learn about healthy relationships.

Filled with easy-to-understand explanations, down-to-earth advice and cheeky illustrations, this growing-up guide by trusted paediatrician Dr Ranj is perfect for readers aged 10+ who want to discover the confidence to be the very best version of themselves.
