In Robert R. McCammon's novel "Swan Song," the haunting phrase, "and his bones were a cage of ice," evokes a vivid image of isolation and emotional desolation. It suggests a profound transformation of the character's being, where physical existence is juxtaposed with a chilling sense of entrapment. This line reflects the deeper themes of survival and the loss of humanity in a post-apocalyptic world.

The narrative explores the struggles of its characters as they navigate through desolate landscapes, fighting against overwhelming odds. McCammon's portrayal of their internal and external conflicts is powerful, revealing the stark realities of fear and hope in a world torn apart. This chilling metaphor serves to encapsulate the essence of their challenges, emphasizing the struggle to maintain warmth and connection amidst pervasive coldness and despair.
