Lemonade code where a boy named Robbie tries to fund his secret project by selling flavoured lemonade. He is genius boy knowing a lot of science and created a machine to serve different flavoured lemonade but there was a girl Daphne who was selling old-style lemonade who became his rival and he was so rude and want to find out why everyone loved her lemonade and rest of the story more of code, fireflies, lemonade dimension, mad music, Robbie calls himself a mad scientist and the world was shown so different it was not the age where smartphones are used, they use VRooms for conversation. Robbies's mama was also doing some secret project. I felt something was missing in the last half of the book. First half was really good and I loved the Illustrations.
