Dashiell Gibson lives on the moon with his family in a facility called Moon Base Alpha. Both Dashiell’s parents are scientists and that is how he ended up living on the moon. His parents are working on experiments and they are helping to make the moon a livable place for other people in the future. There are other scientists and their families who live on the moon too. The commander, Nina Stack, is in charge of the entire project. One night, Nina goes missing and the last person to see her was Dashiell. Everyone is looking for Nina but they can’t find her. This is very puzzling because the Moon Base unit covers a small area so there are only so many places that she could be. It looks like it is up to Dashiell to solve this mystery.
