From the National Ambassador of Young People's Literature, comes the spaciest middle grade series this side of earth. BE SPHDZ. Michael K. just started fifth grade at a new school. As if that wasn't hard enough, the kids he seems to have made friends with apparently aren't kids at all. They are aliens. Real aliens who have invaded our planet in the form of school children and a hamster. They have a mission to complete: to convince 3,140,001 kids to BE SPHDZ. But with a hamster as their leader, "kids" who talk like walking advertisements, and Michael K as their first convert, will the SPHDZ be able to keep their cover and pull off their assignment?

Don't miss the stunning, riveting, hilarious, and 100% fresh conclusion to the interactive Spaceheadz saga! The SPHDZ accomplished their goal of recruiting 3.14 million and one SPHDZ. But the brainwave has been stolen by the chief of the Anti Alien Agency, and it's up to Michael K., the SPHDZ, and their allies to get it back. With three potential Chief sightings, the team is spread around the world, leaving Michael K., Venus, TJ, and the SPHDZ to hold down the fort and finish fifth grade. But with a mysterious new principal and graduation fast approaching, will they be able to find the missing brainwave before the Chief uses it to destroy a planet?
