Chapter 1

Welcome to the Change

Maya noticed it on a Tuesday.

She was tying her shoes before school when she caught a smell — just a little — that hadn’t been there before. Not bad, exactly. Just new. Hers, but not familiar. She sat there for a second with one shoelace still loose, trying to figure out if she should be worried about it.

She wasn’t. Not really. But there was a small, quiet question sitting in the back of her mind all day: Wait, is this normal?

If you’ve had a moment like that recently — a small surprise about your own body, a feeling you can’t quite name, a question you’re not sure who to ask — you’re not the only one. You’re not even close to the only one. Every single person who has ever grown up has had a version of Maya’s Tuesday. It might have been a smell, or a sore spot, or a strange dream, or just a feeling like your own skin fits a little differently than it used to.

That feeling has a name. It’s called puberty, and this book is here to walk you through it.

What puberty actually is

Here’s the first thing worth knowing: puberty isn’t one event. It’s not a single day when you wake up, and suddenly you’re different. It’s a process — a long one, usually a few years — where your body very slowly shifts from a kid’s body into a more grown-up one. It happens at its own pace, on its own schedule, and that schedule is different for every single person.

Underneath all of it, there are hormones — chemical messengers your body starts producing in larger amounts — quietly telling different parts of you to grow, change, and develop. You won’t feel the hormones directly. What you’ll notice are the results: maybe your height, maybe your skin, maybe your moods, maybe all of it at once, maybe one thing at a time, spread out over months.

Some girls start noticing changes around nine or ten. Some don’t notice anything until they’re thirteen or fourteen. Both of those are completely normal. There is no official starting gun, no moment where you’re “supposed” to begin. Your body will start exactly when it’s ready to start, and that timing has nothing to do with anything you did or didn’t do.

You are not broken, behind, or weird

It’s worth saying that directly, because it’s the thing so many people worry about quietly, without ever asking anyone out loud.

If your body is changing faster than your friends’, you are not broken. If it’s changing more slowly, you are not behind. If something about this whole process feels confusing or strange or a little embarrassing, you are not weird. You are a person going through something that every single adult around you has already been through — your mom, your teacher, your grandmother, the woman at the grocery store. Every one of them had their own version of your Tuesday.

The reason this can feel so isolating is simple: people don’t talk about it very much. Not because it’s shameful — it isn’t — but because it can feel awkward to bring up, so a lot of people just... don’t. That silence can make it seem like you’re the only one experiencing any of this. You’re not. You’re just one of the only ones who happens to be going through it on this particular Tuesday.

How to use this book

You can read this book from start to finish, like a story. That works well if you like knowing what’s coming before it happens.

Or you can skip around. If something is happening to you right now and you want answers today, find the chapter that matches it and start there. This book isn’t a test, and there’s no wrong way to read it. Flip to the period chapter first if that’s what’s on your mind. Skip straight to the chapter about moods if that’s what you’re dealing with this week. Come back to chapters later, after something happens that makes you want to reread them. All of that is exactly the right way to use this book.

There’s also a workbook section near the end, with trackers and space to write — not homework, just somewhere to put your own thoughts if you want to.

And at the very end, there’s a short section written for the adults in your life, in case you ever want to hand this book to them and skip the part where you have to explain everything out loud yourself.

Maya, again

By the end of that Tuesday, Maya hadn’t figured out exactly what was going on with her body. But she’d stopped being quite as worried about it. She figured that if this was happening to her, it was probably happening to other people too — and she was right.

You’ll see Maya again throughout this book. She’s not going to have all the answers either. But she’s going to go through a lot of the same things you might be going through, in roughly the order most people go through them — and you’ll get to watch her figure it out, one chapter at a time.

For now, here’s the only thing you really need to know going in: nothing that’s about to happen to your body is a mistake, a malfunction, or a secret you have to keep. It’s just growing up. And you’re allowed to take it one Tuesday at a time.
