Finn and the Intergalactic Lunchbox (The Finniverse Series, Book #1) by Michael Buckley
From the New York Times bestselling 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.
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.
