Myra Hodger is in her first year at an elite school on the Moon to train and develop her Creer in math as a Number Whisper-like her famous Number Whisperer parents. But she's crumbling under the pressure, she doesn't fit in, and worst of all, the tattoos that signal her Creer growing aren't developing. In her heart, she knows she doesn't have a Creer, and soon, everyone else will, too. Wandering the school while cutting class one day, she discovers a secret lab hidden behind one of the unused classrooms, and beyond that, a secret garden overflowing with dangerous toxic plants. But as Myra learns the garden isn't a threat, she begins to wonder if she does have a Creer-one that died out when the Earth did. If she wants to learn the truth about the garden and herself, she'll have to hurry. There are those who'll do anything to take these secrets to the grave.
