The remarkable tale of cavalry officer Rawicz and six fellow prisoners, who escaped from a Siberian gulag and trekked across the taiga to freedom. It's an astonishing tale of strength and determination. These men, already in poor condition in Yakutsk, manage to sustain themselves on foot over 4,000 miles of barren land and mountains. Peter Weir adapted the book for his film, The Way Back, starring Colin Farrell, Jim Sturgess, Saoirse Ronan and Ed Harris.  (SIB13, $16.95)
