"There aren't many coders like that, not that I've ever met. You just might find that the mouse is really a lion, and even worse, that the lion has your head in her mouth."

TWELVE-YEAR-OLD MOUSE GAMMA has spent her entire life struggling to communicate. She's never understood how to stop the bullies and negligent foster parents without causing more trouble than it's worth. That is until she discovers the magic of code-a language that's more powerful than anything she's ever imagined.

To everyone's surprise, Mouse is anonymously chosen to attend the prestigious Rickum Academy-an incubator for the brightest and most promising young minds in tech. Her excitement is short-lived as the mystery of how she ended up at Rickum very quickly unravels around her, threatening the safety of her new life and the innocent lives of those around her. With the help of her new friends, Ada and Boone, Mouse is in a race against her classmates, her teachers, and the most powerful man in tech to not only uncover the truth about who she is, but who she is not.
