Billi Rose arrives at school one day to find that Ms. Hild, the librarian, is away sick and there is no one to run the Library and its Maker Space. The books begin piling up and the Maker Space is a mess.

Billi Rose becomes inspired to solve this problem. Working through Gym, Art, and Lunch (her favourite subjects) Billi engineers a robot to help bring the library back into working order for Ms. Hild. Billi's robot doesn't work the way she wants it to though and starts destroying the library! What is Billi going to do? Will her Robot save the day, or will it lead to the destruction of the library and its Maker Space?
