Audiobook. Great story about a small US settlement on Mars that no longer communicates with other countries’ settlements after a tragedy. Told through an 11 year old’s viewpoint of the situations that happen and how he initiates some mending of fences and improving everyone’s lives by cooperation. Author’s note at the end explains her thought behind the book and the eerie parallel idea of quarantining on Mars and COVID-19 (the book was written pre COVID).
