The Sparrow by Mary Doria Russell
When I worked at the bookstore, we sold this book with the pitch that it was ‘Jesuits in space’. I have read this more than once and hosted a couple of book group discussions around it. Wrenching and unforgettable, The Sparrow takes us inside a Jesuit mission to space that goes horribly wrong. Touching on themes of ethics, interspecies communication and the role religion and faith play in exploration, this is a must-read.
