Lazlong has truly amazed me for some time; his fertile mind gives me enormous pleasure. The period about which he writes is as unknown to some people as the far side of the moon. To think of the preparation needed to travel from the east coast to the Pacific North west without any resources except what you could carry in an unsprung wooden wagon pulled by oxen only to find out that having travelled one thousand miles you are at the commencement of the real part of your journey is amazing! But families did it, and succeeded in making one of two great nations in North America!
The story centres around Millie and Jason and the trials and tribulations of these two love-birds. And it is only as the tale magically unfolds that one realizes how mature and self sufficient he is for all of his sixteen years.
You meet bigots, liars, thieves, and wonderful friends, and you participate in the coming of age of an extended marriage in all it's Heinleinesque glory.
Take your time and read this epic series at least a couple of times to enjoy the nuances of good writing.
