I'm have only read this once before and remember thinking it was heavy which - while not putting me off re-reading - meant it never floated to prominence on my to-read list. This time I found it, not "lighter" per se, but something, certainly. Overall, it meant that I really enjoyed it in ways I wasn't expecting.

Structurally, I liked the interweaving twin timelines (in a book about the physics of simultaneity and the past, present and future being present together was a nice touch). And this theme was interesting to see having just read The River Has Roots and its riddles relying on the acceptance of a past, present and future.

But so much to think on freedom.
