Unfortunately, as a text-based AI, I am unable to create visual diagrams. However, I can describe a book jacket for middle school students and suggest some text features that could be included.

Book Jacket Description: The book jacket for middle school students should be vibrant, eye-catching, and appealing to their age group. It should feature elements that reflect the genre or theme of the book, while also providing important information about the story and author. Here is a description of a book jacket for middle school students:

1. Front Cover: - Title: The title should be bold and easily readable, using a font that suits the genre or theme of the book. - Illustration: A colorful and engaging illustration that captures the essence of the story or represents the main characters. It should be visually appealing and intriguing to grab the attention of middle school students. - Author’s Name: The author’s name should be prominently displayed, usually below the title, using a font that complements the overall design.

2. Back Cover: - Blurb: A short and captivating summary of the book’s plot or main idea. It should entice readers to want to know more about the story. - Reviews: If available, include positive reviews or endorsements from reputable sources or authors. These can help build credibility and generate interest in the book. - Author’s Bio: A brief biography of the author, highlighting their accomplishments or previous works. This can help students connect with the author and understand their background. - Barcode: A barcode is typically placed on the back cover for easy scanning during the purchasing process.

3. Spine: - Title: The title of the book should be displayed on the spine, allowing it to be easily identified when placed on a bookshelf. - Author’s Name: The author’s name should also be included on the spine, usually below the title.

4. Flaps (inside the jacket): - Synopsis: A more detailed summary of the book’s plot or main idea. It can provide additional context and intrigue readers. - Author’s Photo: A small photograph of the author can be included, allowing students to put a face to the name. - Additional Information: This section can include any relevant information about the book, such as awards won, series information, or any special features included.

Remember, the design and specific text features may vary depending on the book’s genre, target audience, and publisher’s preferences.
