At first glance I thought this book would be all about dimensions and how to master them, but it turned out to be way more than just that. Star and Marco's Guide to Mastering Every Dimension talks about every character in the show and their secrets, all the places we get to see throughout the episodes, the old queens, Star's clothes, some of Marco's karate moves, Princess Pony Head's real name(and guess what! She's got sisters!) and so much more you can see in this book! It also has contents that we never got to see in the show! Like Marco's recipe for the Marco's super awesome nachos, more old queens, and wanted posters! Also the answer of some questions you may or may not have been asking yourself.

If you like/love Star vs The Forces of Evil, this book is a great thing for you. It's funny(I caught myself laughing out loud spontaneously while reading some chapters), it's colorful and so nice reading that I couldn't stop reading until I finished it.

Anyway, you should have one for yourself.
