Lost on Mars — Paul Magrs

With the scale and scope of a great sci-fi epic, this is the story of Lora and her family, third generation settlers on the red planed, who are struggling to survive o a smallholding in the desert landscape, surviving storms and sinister rumours of unexplained disappearances - until one night Lora sees the Dancers. When her father and grandmother disappear, Lora and her family are driven out to seek a new life across the plains. But none of them are ready for what they find - the beautiful and dangerous City Inside.
