Adventures of Diana Part II: Diary of a 3rd Grader is the second book in a series that takes you through the world of nine-year-old Diana through her own eyes. From the beginning of a new school year to an unforgettable summer vacation, Diana shares her thoughts and feelings while experiencing the ups and downs of this new chapter in her life. Diana works through the challenges of navigating conflict with new friends, feelings of insecurity, and even a bit of Friday the 13th bad luck, but always finds a way to learn from these experiences and have a lot of fun along the way!

The author, Rachel Yang, is a nine-year-old girl who shares her own thoughts and experiences through the eyes of Diana - a curious, resilient kid who faces the challenges of a new school year, new friendships, and new emotions head-on. Rachel's father, Ross Yang, is the illustrator.
