An interesting book.

In April 1846, a group of American pioneers leaves the Illinois River Valley in wagons to find a better future in California.

Trapped by snow in the rugged terrain of the Sierra Nevada Mountains, near Truckee (now Donner) lake around November 1846, they run out of food.  By the time the last member of the Donner–Reed party staggers out of the Sierra Nevada Mountains six months later nearly half of the group of 87 men, women, and children have died of cold and starvation and many of those who survive take extreme measures to do so.    

I read the book with great interest, it gave me an idea of what this group of people went through, and the ordeal they had to face in their search of a better future.

Historians have described this episode as one of the most spectacular tragedies in Californian history and in the record of western migration.
