Here's why those books come to mind:
* "The Absolutely True Diary of a Part-Time Indian": This book follows Junior, a Native American boy who leaves his reservation to attend a predominantly white high school. The school is full of unique individuals, some kind, some mean, all with distinct personalities that Junior observes and interacts with.
* "The Perks of Being a Wallflower": This novel focuses on a shy freshman named Charlie who navigates the ups and downs of high school with the help of a group of friends. Each friend is distinctly different, and their personalities are explored in the context of their experiences and relationships.
However, to give you the most accurate answer, I need more information! Could you tell me:
* What genre are you looking for? Is it a contemporary novel, a coming-of-age story, or something else entirely?
* What is the tone of the book? Is it humorous, dramatic, or something in between?
* What are some other details you remember about the book? Did it have a specific theme, or did it involve any unique events or settings?
The more details you can provide, the better I can help you find the book you're looking for!
