There is hardly a more formative phase in a girl's life than puberty. Many women are reluctant to remember this turbulent time, when their bodies are undergoing major changes and their moods can change from sky-high to deathly sad at any time.

Curtain up for Girl on Fire, a different kind of sex education book. With wit, sensitivity and the courage to tackle difficult topics, Dr Sheila de Liz - better known on TikTok as Doktorsex - tells girls what they need to know (and are often afraid to ask) in a way that is appropriate for the target group.
