As a fashionista and future rock star, California girl Mackenzie "Zee" Blue's life is busy. Zee keeps in touch with all her friends with texts, IMs, and emails—and now, Bluetopia, the coolest social networking site ever!

In Mixed Messages, fourth in the illustrated middle-grade Mackenzie Blue series, Zee and her friends from Brookdale Academy launch Bluetopia, a fab social media site—which is perfect, because Zee's band, The Beans, is about to have its biggest show ever. Everyone is talking about it on Bluetopia.

At least it would be perfect if a glitch in the Bluetopia system didn't threaten to ruin the show—and Zee's life!

Tween fans of the Dork Diaries and Diary of a Wimpy Kid series will love the Mackenzie Blue books.
