Nova invents a robot named Cody to help her with her chores so she has more time to do science, but then Cody tries to take over her secret lab—and the world!

Science-loving Nova is back and ready to hit the lab! But cleaning her room and doing other tasks is taking up all her time. When she hears about a robot-building contest, she knows exactly what to do. She gets to work and invents the perfect robot, using coding from her AI assistant Comet, and programs Cody to do her chores so she can get back to her experiments. But Cody is a little too efficient. He quickly moves on from chores and starts helping Nova with her lab work. Before she knows it, he won’t listen to her and has completely taken over! What has she created? And can she stop him before it’s too late?
