This book is about two kids and one hamster from a different planet. Jennifer and Bob, the two aliens, team up with Micheal K. to save the world! To save the world they have to get 1 million people to be SPHDZ but Agent Umber is always trying to mess them up. They have many exciting adventures including everything from space guns to giant donuts. This is the second book in the series.
This book is part of a series and I have not read the other books. I was a little confused in the beginning, but then everything fell into place. I suggest you read the first book in the series before reading this one, but this is still a great book on it's own.
My favorite part was the beginning because when I read it, I felt like I was part of the story. My favorite character is Agent Umber, because he has a pickle phone and I think that's funny. Electromagnetic sources sound spooky...
