James Houston tells the story of the Donner party from the point of view of James Reed, a member of the wagon train who did not spend the winter of 1846 in the Sierra Nevadas. He had been sent on ahead, and was one of the people trying to reach the stranded families from the other side of the mountains. His frustration is excruciating as he battles for support in an area that is consumed with breaking away from Mexico. Rescue parties he mounts are turned back again and again by blizzards. Reed refuses to accept that rescuers may not be able to reach the settlers until the terrible winter is over. He knows that his family and the others cannot survive that long.
Survival in the freezing camp is recorded by his youngest daughter, Patty, who looks back on that winter as a woman in her 80's. The fact that there were any survivors is incredible. This was an exceptionally frigid winter, and the families crammed into hastily thrown-together shacks, without heat, polar fleece, or thermals, eating anything, anything to stay alive. There was little heroism. Each group was on its own. Patty's trail diaries reveal the smell, the anger, the hunger, the despair that no one will come to help in time.
The desperation is heightened for the Reed family because they are one of the reasons the group did not make it over the summit before winter set in. What keeps James Reed from hero status is his hubris in building an enormous two-story wagon so his family could travel west in comfort. This "Palace Car" slowed everyone down, delaying the group's arrival in the Sierra Nevadas until too late in the year. The Reeds' descent from being the most envied group on the trail to the one with the fewest remaining resources makes Jim Reed even more complex, frantic to save his family from the result of his pride, yet so wrenched by guilt that he is tempted to flee south to fight the Mexicans.
