How would you describe yourself? Do you like to stand out, or fit in? Are you an Instagram junkie, or is Snapchat more your thing? Are you watching Zoella on YouTube, or reading Rookie on your phone? We're all different, and no-one's teenage years are the same. But we do all have one thing in common - being a teenager is about discovering who we are, and who we want to be.

It can be tricky, building and forming your own identity and sense of self, and sometimes, advice from someone who has been there and done it in the not-too-distant past can come in useful. Enter Rosalind Jana, who's crammed more into her 20-odd years than most (including winning the Vogue Talent Contest for Young Writers AND 'Well Dressed' at the Observer Ethical Awards, but don't tell her we told you that...). Notes on Being Teenage covers all aspects of teenhood, from the serious (mental health issues, bullying, staying safe online), to the slightly-less-so (dating, style, fashion, starting a blog) and everything in between. Rooted in her own experiences as a blogger, part-time model and eco-fashion-expert, but also as a teen who struggled with scoliosis, bullying and her dad's depression, Rosalind is well-placed to offer advice and guidance to anyone navigating their teenage years.

She's also spoken to loads of teens about their experiences, too, and their stories, problems, advice and wisdom are gathered here as well, along with interviews with inspirational and interesting people like Louise O'Neill, Juno Dawson and Rosianne Halse-Rojas. All this combines to form a warm, witty, wise book not just on how to survive but how to thrive as a teen. Essential reading for smart girls of any age.
