From the founder of the popular online site HelloFlo, comes a modern and insightful guide to periods and puberty.

When will I get boobs? Does wearing a tampon hurt? What’s the deal with menstrual cups? Seriously, when will I get boobs?

There’s no doubt that going through puberty is one of the scariest, messiest, and most confusing times in a girl’s life. It’s no wonder there are so many questions. And for most girls, it’s hard to know where to go for reliable, fact-based straight talk, no pastel-colored sugar coating. Enter The HelloFlo Guide to Puberty, a smart and savvy new guide that’s definitely not your mother’s puberty book.

This is a celebration of women’s bodies and all the confusing, uncomfortable, silly, transformative, and powerful changes that occur during puberty.
