Izzy Jeen the Big-mouth Queen Books in Order

The Izzy Jeen the Big-mouth Queen books are short chapter books about a kid who means well, feels everything loudly, and usually acts before she has fully thought things through. Izzy is stubborn, funny, quick to speak, and very sure that she knows what is fair. That makes her easy to root for, even when her big plans start going sideways.

That mouth gets her into trouble.

The stories stay close to the kind of problems that feel huge when you are a child. A friend may be leaving town. A new classmate may be getting picked on. Someone important may not be listening. Izzy's first instinct is almost always to jump in and fix things herself. She is not a quiet observer, and she is definitely not the sort of character who waits patiently for adults to sort everything out. In books like They Better Leave Sandra Alone or Else and Emma Sanchez Is NOT Moving Away!, that impulse to protect the people she cares about drives the whole plot.

The setting is ordinary in the best possible way. School hallways, neighborhood streets, phone calls, signs, classrooms, and friendship circles all matter here. Because the world is so familiar, the tension feels real for young readers. Izzy is not fighting monsters or saving the planet. She is trying to save a friendship, defend a classmate, or force the world to make sense. For the audience these books are written for, those stakes are more than enough.

The tone is lively and warm, with lots of energy but not much meanness. Izzy can be impulsive, and her plans can backfire badly, but the books are not built around mocking her. They are built around understanding her. She wants justice. She wants loyalty. She wants people to stop being unfair. The real question in each story is whether she can chase those goals without making a bigger mess.

Her friends matter a lot too. Emma, Lissa, and Sandra are not just background names dropped in to keep the plot moving. They help show the different sides of Izzy. Around them, her loyalty looks sweet, her temper looks risky, and her growing self-control starts to matter. The books understand that childhood friendship can be messy, intense, and deeply serious, all at once.

What links the series is Izzy herself. From book to book, she keeps learning the same hard lesson in slightly different ways: standing up for people is good, but charging ahead without listening usually makes things worse. That gives the stories a nice shape. Young readers get humor, motion, and a lot of feeling, but they also get a character who is slowly figuring out how to be brave and kind at the same time.
