The author is always comfortable following her fancy, whether considering a spider’s web illuminated at first light, the mechanics of sunflowers, an astounding daybreak cloud, a lover slipping away at dawn in The Pillow Book, Monet painting “the lavish spell of the senses detained by a pink and blue sunrise” or the “chatterbox chorale” coming through the window from all manner of bird, the best of which has got to be the crow: “ I’m up, dammit.
