On their way to Rainbow's Edge to seek the help of the Ray Keepers, Professor Plano, Zed and Zee meet a flight of sickly, grey dragons. They're all caught up using their Bottle-Bottle screens that give off a strange, eerie glow. Lord Myopic must be up to no good again! The trio rush to find the Ray Keepers to save the dragons, but are they too late? Myopia (short-sightedness), device dependency and lack of outdoor activity are public health concerns worldwide. Stories from the plano adventures are based on years of scientific research, written specially to empower young readers. © 2018 by Mo Dirani & Hwee Goh.
