"Masterpiece"
Books in the original Foundation trilogy need no introduction; they have stood the test of time and are broadly accepted as some of the greatest masterpieces in the science fiction genre. You can find millions of words written about these books all over the Internet.
I have some comments that relate to frustrations I encountered while reading reviews for this book. First, I wish that I could comment on reviews that others have written like I can on Amazon. What follows would more appropriately be entered as such a comment, but it's here because there is no other way to respond to existing reviews.
To Joseph: First of all, it is misleading and unhelpful to give a book a poor rating because you didn't realize it was part of a trilogy. You are supposed to review the quality of the work, not vent your frustration at being unaware that the book is part of a series. That's your problem, not the book's.
Secondly, it would have taken you all of 5 minutes to discover not only the series to which this book belongs, but also the published order of all the books in the series, with a simple Google or Wikipedia search. This is made even easier by the fact that this is one of the most famous serials written during the entire 20th century in any genre, and at least in the top 5 of most famous science fiction serials of all time.
That said... it would not hurt my feelings if Audible would include both the chronological order and published order of books that belong to a series. It would really be nice to be able to add all books in a series to my wish list with a single click, and for those books to remain grouped together in the wish list so it is clear that they are all members of the same series. That would make it easy to buy them all at once too. Keeping them ordered by original book publication date within the grouping would also be VERY helpful. NOT the date the audio version was published -- the date the ORIGINAL BOOK was FIRST published.
Chronological order is interesting but not terribly useful, because you do not want to read them that way. The author expects you to read them in PUBLISHED order, so that is what you should do for maximum effect. For example, there are essentially "spoilers" in prequels that will ruin mystery and suspense created in the books published earlier in the series.
For anyone not willing to type the words "foundation series published order" into Google, below is the published order of the series. This is the proper and expected order in which to read them.
Foundation
Foundation and Empire
Second Foundation
Foundation's Edge
Foundation and Earth
Prelude to Foundation
Forward the Foundation
Enjoy!
