Posted by John David Anderson is a realistic fiction story. It’s about a boy nicknamed Frost and the rest of his “tribe” of friends witnessing a Post-It note war in their school. The notes on lockers just kept coming after phones were banned and, in addition, a new girl named Rose came to the school. She was a bit of an oddball, but none of Frost’s tribe really thought she would end up friends with the other oddballs in the school: them. This book is a journey of friendship, bullies, courage, and, most of all, Post-It notes.
