Let's Be Honest
I won a Scholastic giveaway about a month back. TBH was one of the books that was geared towards older kids. On Amazon it recommends the book for ages 12-17. The book is written by Hunter March, but it is a collection of stories from many authors. You may recognize his name from his many YouTube videos.
This collaboration of stories covers everything a teenager might be going through. There was a wonderful story by Aija Mayrock about bullying and how to overcome it. Hunter tells about his school, relationship, and job experience. These are stories written by young adults about what they have experienced, from first kiss to worst break up.
