Here is the stunning international bestseller in the tradition of Watership Down but with a dark, original twist. Unique, daring, and unforgettable, it tells the story of an ordinary family who accidentally threaten the security of a hidden civilization as intelligent as our own a colony of ants determined to survive at any cost... Jonathan Wells and his young family have come to the Paris flat at 3, rue des Sybarites through the bequest of his eccentric late uncle Edmond. Inheriting the dusty apartment, the Wells family are left with only one warning: Never go down into the cellar. But when the family dog disappears down the basement steps, Jonathan follows and soon his wife, his son, and various would-be rescuers vanish into its mysterious depths.
