From the New York Times best-selling author of the Sisters Grimm and NERDS comes a new action-packed middle-grade series with aliens, robots, and kids saving the world!

Finn Foley has a lunchbox, and when he opens it, weird things come out...like a seven-foot-tall robot and a strange, blinking device that glues itself to his chest. The lunchbox also opens wormholes - shortcuts through space - that take Finn to the farthest corners of the galaxy.

Sounds awesome, right?

Not so much. Rocketing through the cosmos attracts the attention of the Plague, a race of gigantic bugs. The thing on Finn's chest belongs to them - it's the most dangerous weapon in the universe - and they want it back.
