It's almost time for school to start again, and Nikki is a little worried—but, as always, she has her BFFS to help. Only, it turns out her friends need Nikki's help. Nikki quickly gets overwhelmed and even starts feeling sick…which is when her little sister, Brianna, takes her chance to steal Nikki's diary! This book is part of a series. I extremely recommend reading this book and reading the whole series!
