The Saviours - Sci-Fi Horror

Nine days after Earth died, Susie wakes up, surrounded by alien spiders who claim to be here to help. Her home is gone, and she has no choice but to rely on these strange aliens, to learn their language, and to navigate a universe more alive, and more deadly, than her ancestors could have imagined. Sailing through space in a hollowed-out moon, Susie and spider-alien 'Michael' must find a way to defeat the world-eater, or at least, somewhere they can hide until something bigger kills it.
