The "Dork Diaries" series starts with "Tales from a Not-So-Fabulous Life" and ends, as of July 2015, with "Tales from a Not-So-Dorky Drama Queen," with a 10th book expected in October 2015. There are also two activity books that are not part of the main chronology.
The reading order of the "Dork Diaries" series is listed on the website of the author, Rachel Renée Russell, in reverse chronological order, with a normal chronological list of titles toward the bottom of the page.
The first book is "Tales from a Not-So-Fabulous Life," followed by "Tales from a Not-So-Popular Party Girl," and then, third, "Tales from a Not-So-Talented Pop Star." Book 3 1/2, "How to Dork Your Diary," is a how-to book that leaves space for readers to write in a side story, rather than being part of the main series.
The "Dork Diaries" continues with "Tales From a Not-So-Graceful Ice Princess," book four, and "Tales From a Not-So-Smart Miss Know-It-All," book five. The sixth book is titled "Tales from a Not-So-Happy Heartbreaker," and once again, an activity book — in this case the "OMG All About Me Diary," with 365 questions for readers and answers from Nikki, the main protagonist of the series — follows it. The "All About Me Diary" does not have a number.
Books seven, "Tales from a Not-So-Glam TV Star," eight, "Tales from a Not-So-Happy Ever After," and nine, "Tales from a Not-So-Dorky Drama Queen," complete the series as of July 2015. Tales from a "Not-So-Perfect Pet Sitter" has a publication date of October 2015 and is number 10 in the main series.
