Hugh
A small service robot with two blue eyes and a brass screw in his pocket. He can fix almost anything except the one thing he wants to fix most.
Hugh Mobile
A small electric service cart Hugh built together with his grandfather — their last big project before everything changed.
William Harper
The old repairman of Maple Creek. He built Hugh, taught him to read, to think, and to never give up.
Nella Brooks
Fast, bright and impossible to slow down. Nella knows every shortcut in Lumina and every pothole on the way.
Max
A robot dog with one broken ear and mismatched patches of paint from every stranger who ever repaired him.
Sophie Miller
Eight years old, one front tooth missing, and a notebook with two hundred and fourteen inventions in it.
Benjamin Carter
Fifty years at the workbench. He does not give advice. He gives you a job and watches how you do it.
Thomas Reed
He brings the worst news in the book, in a grey suit jacket that is always buttoned, holding a folder against his chest like a shield.
Margaret Green
Thirty-two years behind a library desk. She remembers everything, and she does not own a telephone.
Jack Turner
He complains about everything and means none of it. His robot lawn mower has opinions and he has never forgiven it.
