“Can't be missed!” —Max Brallier, #1 NYT bestselling author of The Last Kids on Earth

Being invisible comes with great responsibility . . . and great fun!

Stanley and Gene have joined forces and finally figured out how to control their invisibility. It’s obvious to Stanley what the duo should do with this newfound control—fight crime of course! Gene, on the other hand, is not so sure. When the only crime around is stealing a pen from the bank, fighting it isn’t all that exciting.

But when a new pair of villains rob Stanley’s family store, things get personal. Can Stanley and Gene track down the thieves and recover the stolen goods before his family is forced to sell their home? And who is the mysterious supervillain boss instigating all of this trouble?

These enemies-turned-partners will have to use all their powers and creative problem-solving to face these foes.
