The Sparrow recap

When the Arecibo radio telescope detects beautiful alien music from a nearby star, the Jesuit order quietly organizes and funds a first-contact mission, sending a small crew of priests and their friends aboard a converted asteroid to the distant world of Rakhat. The novel alternates between that mission and the aftermath years later, when Emilio Sandoz returns as its sole survivor, his hands mutilated and his spirit broken, and the Jesuits convene to learn what went wrong. On Rakhat the crew live peacefully among the gentle, foraging Runa, but by helping them the humans unknowingly upset the harsh balance the predatory, dominant Jana'ata maintain over Runa numbers, provoking violent slaughter. One by one the crew are killed. Emilio falls into Jana'ata hands, is ritually maimed, and is degraded and sexually abused, and a damning misunderstanding over a native child's death makes him appear a murderer and a prostitute when a second mission finds him. He is returned to Earth having lost nearly everyone he loved and his belief that God had guided them.

The story is built on two interwoven timelines. In the near future, a young astronomer detects hauntingly beautiful music arriving from a nearby star, proof of an alien civilization, and the Jesuit order privately mounts a first-contact mission to the source, a distant world, sending a small crew made up of priests and a handful of close friends and specialists. In the later timeline, that mission has already ended in disaster: its only survivor, the priest and linguist Emilio Sandoz, has come back to Earth gravely maimed and profoundly broken, at the center of scandal, and his religious superiors gather to draw from him, slowly and painfully, the account of what truly happened out among the stars. From the opening, the reader knows the venture ended in ruin and that Emilio alone returned; the book's movement is the gradual uncovering of how and why.

The mission to Rakhat ends in catastrophe, revealed gradually as Emilio is finally able to tell it. After a period living among the peaceful Runa, the humans, meaning only kindness, teach them to grow gardens, which lets the Runa population rise. This violates the brutal system by which the ruling predator species, the Jana'ata, keep Runa numbers in check by culling them, and it triggers a massacre. The crew are destroyed: the priests and Emilio's dear friends, including Anne and George Edwards, Jimmy Quinn, D.W. Yarbrough, Marc Robichaux, and Alan Pace, all die, and Sofia Mendes, pregnant, is lost in the violence and believed dead. Emilio alone is taken by the Jana'ata. His hands are deliberately mutilated in one of their customs, and he is passed into the household of a Jana'ata aristocrat where he is repeatedly raped. When a second expedition from Earth reaches him, a native child he had loved is killed in the confusion, so that to outside eyes he appears to be both a murderer and a willing prostitute. He is brought home as the sole survivor, physically ruined and stripped of the faith that had made him believe God led the mission to Rakhat. The framing inquiry ends with the truth of his suffering finally understood by his fellow Jesuits, though it cannot undo what was lost.
