I admire Millhauser's fiction...he is a fabulist and a minaturist--totally unique voice--nobody writes like him.
This story is rather short, but every sentence glitters with hard beauty like a jewel. And such suspense! You know something is going to happen, something important.
The idea of time--the mind's concept of time-- is explored beautifully through a young boy's ordinary afternoon at his family's picnic.
Satori, the Zen Buddhist term for a flash of sudden awareness--that's what this character experiences.
