In a frozen, apocalyptic landscape, destruction abounds: great walls of ice overrun the world and secretive governments vie for control. Against this surreal, yet eerily familiar broken world, an unnamed narrator embarks on a hallucinatory quest for a strange and elusive ‘glass-girl’ with silver hair. He crosses icy seas and frozen plains, searching ruined towns and ransacked rooms, all to free her from the grips of a tyrant known only as the warden and save her before the ice closes all around.
