Meet Roger Tarkington. The almost 11-year-old has a plan for middle school greatness. A perfect plan that--lasts for all of about five minutes. 286 seconds, to be exact. It's all ruined when Kyle-the-Vile Brossman appears unexpectedly on the first day of school. Making matters worse, Kyle pledges to make Roger's year miserable, just like he did at Bellingware Elementary School. Roger's unlucky start to sixth grade turns magical when his calendar turns into a time travel portal that allows him to repeat days. Influenced by his Middle School Greatness Tip #31 (Don't wait for it to happen, make it happen), Roger devises a new plan to use his magic calendar to beat Kyle, clearing his path to middle school greatness. Foolproof plan for middle school success, right? Maybe in real life, but remember, this is middle school! Will Roger succeed in using his magic calendar to stand out at Jefferson Middle School and achieve middle school greatness? Or will he fall under the constant attacks from Kyle and the unexpected, everyday obstacles of middle school? Join Roger and his best friend, E3 (Elizabeth Emily Elliot), in this modern day "Diary of a Wimpy Kid" meets "Groundhog Day" middle school time travel adventure.
