Written as a first-person account of Miguel's thoughts and experiences, And Now Miguel is a realistic novel. The unsophisticated vocabulary reflects Miguel's age, and the dialect reflects the characters' Hispanic heritage.

Throughout the book, Krumgold includes vivid and detailed factual information about shepherding, lending a documentary feel to the novel. This information adds color to the story and develops an analogy between the care a shepherd gives his sheep and the care and love that one should extend to other human beings.

Although simple, the language of the book gains power through the repetition of key phrases and images. Recurring symbols—clouds, music, laughter, and the act of throwing an object—unify the narrative. The novel's themes develop through day-to-day changes in Miguel's maturing perspective.
