A clear and simple guide to growing up, and the changes you can expect during puberty.

With cartoony artwork and diagrams, this book explains puberty in a simple, clear and friendly way. Designed to help reassure readers that what they're going through is normal, whether that's coping with a changing body, mood swings, new emotions and even questions about their sexuality and identity.

The writing and art style, and the level of detail given in each topic, has been tailored to be suitable for kids aged 11 and up, who have just begun their journey into puberty - or are likely to start soon.

Topics covered include: growing taller, getting hairier, bras, periods, shaving, all about vaginas, vulvas and penises, sex, sexuality, love, relationships, friendships, hormones, looking after yourself, staying safe and keeping healthy - written in consultation with experts in sex education and gender studies, alongside medical doctors.

Sam Baer grew up on the tiny island of Jersey before setting off on adventures in not-quite-so-tiny England. Since 2011, he's been writing books about everything from imps and elves to Victorian fashion. It's a dream job (almost as good as being a superhero).
