A Psalm for the Wild Built, by Becky Chambers

The moon of Panga was taken to the brink of environmental catastrophe before its human population came to its senses and restored the balance. Now half the moon has been given over to nature, while humanity has built a sustainable society in the other half. At some point in its history the robots, who were part of the overdevelopment crisis, attained consciousness and, rather than accept citizenship, opted to leave and explore the regenerating wilderness. Now gardening monk Sibling Dex has an overwhelming desire to leave the city and changes his vocation to tea service monk, taking to country roads to dispense tea and sympathy to whomever needs it. Despite excelling in their new vocation Dex is still unsatisfied, feeling a pull to the wilderness. There they meet Mosscap, a robot that has volunteered to check in on the human population. This gives Dex a new perspective on life, the moon and everything. Becky Chambers tackles some deep philosophical issues in this deceptively simple novella of friendship and journey. Short and sweet, it lights a pathway to a better way of living and promises more to come.
