Michael Prasad knows he shouldn’t go out on the Mars surface alone. It’s dangerous. His parents have forbidden it. And the anxiety he feels almost every time he puts on a spacesuit makes it nearly impossible for him to leave the safety of the colony. But when his best friend, Lilith, suggests they sneak out one night, he can’t resist the chance to prove everyone - including himself - wrong.

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?

Bell has spent his whole life—all eleven years of it—on Mars. But he's still just a regular kid—he loves cats and any kind of cake, and is curious about the secrets the adults in the US colony are keeping. Like, why don't they have contact with anyone on the other Mars colonies? Why are they so isolated? When a virus breaks out and the grown-ups all fall ill, Bell and the other children are the only ones who can help. It's up to Bell—a regular kid in a very different world—to uncover the truth and save his family...and possibly unite an entire planet.

But these dogs are Barkonauts - and Barkonauts always complete their mission.

Cog looks like a normal 12-year-old boy. But his name is short for “cognitive development”, and he was built to learn.

Surrounded by scientists who want to study him and remove his brain, Cog recruits four robot accomplices for a mission to find her. Cog, ADA, Proto, Trashbot, and Car’s journey will likely involve much cognitive development in the form of mistakes, but Cog is willing to risk everything to find his way back to Gina.
