Tales from a Not-So-Happily Ever After (Dork Diaries Series #8) by Rachel Renée Russell
After a bump on the head in gym class on April Fool’s Day, Nikki has a wild dream in which she, her BFFs Chloe and Zoey, her crush Brandon, and mean girl Mackenzie all end up playing the roles of some familiar classic fairy tale characters. Princesses, frogs and strange predicaments are afoot! Of course, the stories don’t go quite as expected—because they each have a very special Dork Diaries spin — move over, Grimm Brothers, a dorky new dreamer is in town!
