Cog

Five robots. One unforgettable journey. Their programming will never be the same.

Wall-E meets The Wild Robot in this middle grade instant classic about five robots on a mission to rescue their inventor from the corporation that controls them all.

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

But after an accident leaves him damaged, Cog wakes up in an unknown lab—and Gina, the scientist who created and cared for him, is nowhere to be found. 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.

In this charming stand-alone adventure, Greg van Eekhout breathes life and wisdom into an unforgettable character and crafts a story sure to earn its place among beloved classics like Katherine Applegate’s The One and Only Ivan.
