From the New York Times bestselling author of The Sisters Grimm and The Weirdies comes a wildly imaginative middle-grade adventure series with aliens, robots, and a lunchbox that might just save the universe!

“Alien bugs! Laser cannons! Bloodthirsty unicorns! Don’t be surprised if this lunchbox sucks you in, too.”—MAX BRALLIER, New York Times bestselling author of the Last Kids on Earth series

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.

To fight the Plague, Finn will need the lunchbox, as well as an unlikely squad of assistants: Lincoln, the bully; Julep, the coolest girl in school; Kate, Finn's unicorn-obsessed little sister; and Highbeam, a robot spy from another galaxy. If they can learn to work together, they just might have a chance, but the bugs are coming, and they'll stop at nothing to get their weapon--even if it means destroying the world.
