The Dork Diaries series, written and illustrated by Rachel Renée Russell, has become a global phenomenon for middle-grade readers. Book 11, titled Tales from a Not-So-Friendly Frenemy , continues the humorous, cringe-worthy, and heartfelt adventures of Nikki Maxwell as she navigates the social jungle of middle school. What is Book 11 About? Released in 2016, Book 11 takes a thrilling turn when Nikki’s arch-nemesis, the wealthy and vicious MacKenzie Hollister, transfers to North Hampton Hills International Academy (NHH) – the very same private school where Nikki’s crush, Brandon, and her BFFs, Chloe and Zoey, now attend.
