It's been centuries since the robots of Panga gained self-awareness and laid down their tools; centuries since they wandered, en masse, into the wilderness, never to be seen again; centuries since they faded into myth and urban legend. One day, the life of a tea monk is upended by the arrival of a robot, there to honor the old promise of checking in. The robot cannot go back until the question of "what do people need?" is answered. But the answer to that question depends on who you ask, and how.

Though she knows her brother holds her mother's favor, Ingrid is determined to at least be considered as heir to the family name. She hatches an audacious plan—free a thief from a prison planet from which no one has ever returned, and use them to help steal back a priceless artifact. But Ingray and her charge return to her home to find their planet in political turmoil, at the heart of an escalating interstellar conflict. Together, they must make a new plan to salvage Ingray's future and her world, before they are lost to her for good.

Shizuka Satomi made a deal with the devil: To escape damnation, she must entice seven other violin prodigies to trade their souls for success. She has already delivered six. When Katrina Nguyen, a young transgender runaway, catches Shizuka's ear with her wild talent, Shizuka can almost feel the curse lifting. She's found her final candidate. But in a donut shop off a bustling highway in the San Gabriel Valley, Shizuka meets Lan Tran, retired starship captain, interstellar refugee, and mother of four.

For some it’s an opportunity. For others it’s a moment to question their faith: In God, in science, in everything. Still others try to keep the world running in the face of absurdity and uncertainty. And then there are the billions looking to the sky and wondering how a thing that was always just there is now... something absolutely impossible.

After touring the rural areas of Panga, Sibling Dex (a Tea Monk of some renown) and Mosscap (a robot sent on a quest to determine what humanity really needs) turn their attention to the villages and cities of the little moon they call home. They hope to find the answers they seek, while making new friends, learning new concepts, and experiencing the entropic nature of the universe. Becky Chambers's new series continues to ask: in a world where people have what they want, does having more even matter?
