I took the book with me on holiday and I couldn't put it down, almost literally reading right up until lights out each night. I was surprised and somewhat disappointed to be done in short time. The literary writing combined with the deep mathematical/philosophical meanings is entrancing.

I don't often get to meet people IRL who have read the book and wish I had more opportunities to discuss it. One (of the many things) that stuck out to me was the idea of foreground and background. Prime numbers to me is background that remains when you construct all the composite numbers, so technically they're 'non-composite' lacking the property of being a product of distinct numbers.
