It is about the return of the ultimate villain. The went around the world. They visited many museums. It went from the yo-yo museum, and pez museum. They then encountered the bowler dudes, in a sand pit. They then use a jar and crack it on their head. They then escaped and then went to a ball game. The villain's wife then fights them. The twins then yell into the microphone and turns out the whole thing was fake. Now almost the whole world hates them. Archie clone then comes and attacks them and then they escape on the road trip moving on to the third book.

The book is fantastic. A perfect second book to an already amazing book. It has action, and suspense everywhere. The book is one my favorites, and I plan on reading the entire series till the end. The characters are perfect, and are kids, and their lives are only slightly understandable. I love the book, and I will read the other books, and all are probably great. I love the story lines, and what the characters go through, and it is a great book, and I recommend it for everyone for any situation. ( )

Young Reader Reaction: Having breezed through Mission Unstoppable, we thought our daughter would love this book. She got about halfway through and decided it had gotten to repetitive / tedious.

Adult Reader Reaction: The action is nonstop - and so is the laughter. The story has a "Phineas and Ferb" meets "Spy Kids" feel to it. Because of that, I could see how our pre-teen decided to abandon the book. I kept reading, largely because I loved the pictures and some of the sight-seeing stops.

Pros: Good guys, bad guys, peril, and survival - with a heavy dose of humor! - will keep kids turning the page in this cross-country adventure.
