Frost

Sixteen-year-old Frost lives in a bombed out apartment in a post-apocalyptic world, with only her pet broot, Romes, and a robot named Bunt, who has her father's memories, for company--but now Romes is dying and her need to find help is forcing her to leave the apartment for the first time in her life, and face the streets which are a hunting ground for rogue robots and the dreaded Eaters.
