This 179 page book took me four days to read. Not because it was difficult. In fact, the prose was exquisite and effortless in its beauty. It was because I wanted to read and cherish all of the novel's short vignettes rather than rush through. The book is a series of dreams, close to 30 in all, that Albert Einstein is dreaming as he struggles with his theory of relativity. Alan Lightman, a physicist himself, describes aspects of the theory and time itself through these descriptive "stories". This is not a book that has what I would call a plot. Einstein himself is presented in various interludes and is a minor character. Time is the major protagonist. This novel is an unique experience with parts of it being rapturous. It is both an intellectual and a aesthetic delight bordering on the spiritual. Go into this with an open mind and you should be amazed.
