"Mid-Grade" refers to a category of literature aimed at children typically aged 8 to 12 years. This genre often features relatable characters, engaging plots, and themes that resonate with pre-teens, such as friendship, adventure, and self-discovery. Books in this category are usually longer than picture books but shorter than young adult novels. In addition to fiction, mid-grade literature can include non-fiction works that educate and entertain. Popular examples of mid-grade authors include J.K. Rowling and Rick Riordan, whose books have captivated young readers and encouraged a love for reading.
