The ending of the book will disappoint those who want a happy ending, or just an ending with all the loose ends tied up. In real life, though, loose ends usually stay loose. My thought is that Solzhenitshyn intended the reader to understand that for the characters and the society who are so damaged by the past there can be no happy endings; the best they can hope for is to continue from day to day, grasping at whatever happiness briefly comes their way.
Solzhynetsin again provides the reader with an in-your-face portrayal of the Soviet state but his primary mission is the exploration of the humanity of people in distress. If there is one common theme it is universal hope - hope for freedom, hope for recovery, hope for the future.
Oleg stands out in all his suffering and good humor. His portrait, against a background of drab, cold, gray and utterly barren physical, emotional and spiritual landscapes, is a tour de force of sympathetic semi-autobiographical writing. Who can forget the pitiful state of Soviet medicine against the care of the nurses and doctors. Again, Solzhynetsin the storyteller and Solzhynetsin the seer unite in an unforgettable portrayal of Russia and Russians.
