Fantastic Book - for general readers or for those like me, who are building their own (Hardcover/Leatherbound) Libraries. These styles of books will last - well maybe not forever (Do You Want To Live Forever - lol)- but long enough to pass it down from generation to generation. Books never really lose their value. Electronics lose their value as Technolgy changes. Books don't require batteries or electricity. All you need to read them is some light. I read a few Heinlein books when I was a kid and unlike the movie versions they give you more insight into the characters, their feelings and motivation. A books I find as with this one, gives you more than an any hour and a half or two hour movie - there are no deleted scenes - and Heinlein delivers that in this book.
