Talk:Diary of a Wimpy Kid: Book 15/@comment-37942482-20191210213358

I sorted the DOAWK books by months and discovered 1-4 was 6th grade, 5-9 was 7th grade, and 10-14 was 8th grade because book 14 ended in june. Book 15 might be the summer before high school and be the last book or be high school and just continue the series.
