I loved the premise: a convent of Sisters (the Order of St Rita, no less!) travelling in a massive slug/spaceship, there was so much to love and expect. It was just a bit less exciting than I'd hoped, a bit less weird and quirky... Maybe it could have been more developed, a novel instead of a novella, so that we'd know more about all the sisters, not just through bits of backstory, but through what they do. Because even with the few reveals, it felt a bit flat, unfortunately.
