What is the author's style in Einstein's Dreams by Alan Lightman?

Einstein's Dreams begins with a lyrical portrait of the city of Berne awakening at dawn, and this lyrical and poetic language continues in the descriptions of all the worlds that Einstein dreams. The novel is about time, and each moment of time is a picture that the author paints with words. Each moment exists importantly and individually within the story, whether it is a moment in Einstein's real world or in his dreams.
