Once

Published 2006149 pagesISBN 978-0-1413-2063-2

For three years and eight months, Felix has lived in a convent orphanage high in the mountains in Poland. But Felix is different from the other orphans. He is convinced his parents are still alive and will come back to get him. When a group of Nazi soldiers come and burn the nuns' books, Felix is terrified that his Jewish, bookseller parents will also be in danger. After escaping from the orphanage, Felix embarks on a long and dangerous journey through Nazi occupied Poland, befriending a little orphan girl called Zelda and a kindly dentist, Barney, who hides and cares for Jewish children. But when the Nazis discover them, Barney makes the ultimate sacrifice for the children.

Beyond its central premise, the book can be read through the connected lenses of Nonfiction, Fiction. Those themes offer useful points of attention as the characters, ideas, or world develop, especially where the book complicates the expectations of its primary category.

A more thoughtful way into this book

This guide uses the edition details and category signals above to help you choose deliberately. It does not replace the author's work or a full review.

Good to know

Works well for a focused weekend or a few concentrated sittings.

Begin with its place in Nonfiction, then notice where the book resists that label.

Try this reading approach

Read for connection, not completion.

Mark one passage that sharpens the book's central concern and one that complicates it. That tension often reveals more than a quick summary.

Three questions to carry with you

  1. Whose perspective organizes the story, and whose perspective remains outside it?
  2. Which sources or lived experiences carry the author’s central argument?
  3. How does the book change the way you understand its larger subject?
