What is the author's tone in The Little School: Tales of Disappearance & Survival in Argentina by Alicia Partnoy?

The Little School is composed of many short chapters which have simple themes and simple character sketches. The structure of the chapters gives the book a tone that reflects Partnoy's background as a poet. The short pieces are almost like extended lyric non-rhyming poems that offer pictures of life in the Little School. The tone of the book is therefore unlike most autobiographical works because it is written partly as an artwork. In fact, the artwork-style tone is amplified by the paintings in the book that accompany the chapters.
