content: Foundation, and all the other books that complete the extense colection are wonderful. I remember when i read this book 8 years ago, and as you see i still love it. If you don't want to read all the books of the series, you don't have to do it, the saga of foundation it's only three books (foundation, foundation and Empire, and Second Foundation), but if you want to read a good, good, GOOD,GOOOOOOOOOOD series of books, read them all, you won't regret it. I really loved all this books.
