The Hydrogen Sonata

Overall very satisfying, although on some points very philosophical novel, but at the end a very good one. Sort of a wonderful “end” to the Culture series. Another view of the whole universe, more interesting background. Just sad that there are no more and never will be any more. By far the best Sci-Fi series out there, especially in variety of the content.

Highly recommended. All of them. Even the less “good” ones.
