This year, Nikki has to solve many problems. Her arch-nemesis, Mackenzie, is spreading rumours about Nikki's crush on Brandon through her column in the school paper! Mackenzie has started a war. Nikki will end it!

So Nikki joins the paper as Miss Know It All to keep an eye on Mackenzie. She has fun at the beginning, answering all her letters and solving other kids' problems but when her mailbox starts overflowing… Can she go on answering letters and stop Mackenzie?

I really LOVED this book!!! It has a girly sense of humour and is a pleasure to read.
