"science fiction at its very best"
first, the reading of the book is excellent, the tone and flow of the smooth voice draw you away from reality if even just for a little while. second, the story is classic for this genre, it defines the genre.for the type of science fiction it represents it is a classic, one of the best.
perhaps in a slightly different off shoot of older sci-fi "Old Man's War" by Scalzi or any number of Heinlein's early works.They have a certain quality about their story's, a richness and thoughtfulness.
Each of the two main characters, one in his youthful strength and simplicity and the other in his more worldly less trusting "there is always an angle" approach, is rich in his own way, neither is a favorite, both are relived in my mind in my everyday pursuits.
moved me? no but the development of the characters and the adventures they have together provide a rich memory that continues for me long after all of the books in the series.
real sci-fi readers, listeners, should not miss this book, this series.
