Book excerpt: What's it like to grow up online and have every tantrum, every spot - even your first period - broadcast to hundreds of thousands of followers? Most parents try to limit their kids' online exposure. But not Eva's. Her parents run a hugely successful blog, Happily Eva After - and Eva is the star of the show. But Eva is getting sick of being made to pose in stupid mum-and-daughter matching outfits for sponsored posts. The freebies aren't worth the teasing at school. And when an intensely humiliating "period party" post goes viral, Eva is outraged. She's going to find a way to stop the vlog, even if she has to sabotage it herself.
