Once (2006) Parents Guide: Is the book OK for kids?

There are no sexual themes, romantic subplots, or instances of nudity present in the book. The narrative focus remains strictly on Felix's survival and his innocent perspective during the Holocaust. Because the story is told through the eyes of a young child, the content is devoid of any mature reproductive or physical intimacy. Readers will find the relationship between Felix and Zelda to be purely platonic and akin to siblings. The text stays true to its middle-grade designation by avoiding any adult romantic…

The book contains moderate to heavy trauma involving the Holocaust. The narrative depicts the execution of civilians, the shooting of a pet dog, and the deliberate burning of homes. Felix witnesses Nazi soldiers shooting people in the street and finds the bodies of a family who have been murdered. There are scenes involving the forceful herding of children into cattle cars and the physical abuse of those in the ghetto. The threat of death is constant, and the book does not shy away from the reality that many…

Very mild. There is essentially no profanity, as the narrator is a young, sheltered boy who avoids using strong language. The primary focus is on the descriptive language of war rather than vulgarity, though some aggressive commands from soldiers are noted. Felix's internal monologue is respectful, reflecting his upbringing in a Catholic orphanage and his Jewish roots. Any harshness in the text comes from the situations described rather than the vocabulary used. The reading level is accessible for young readers…

None. There is no use of drugs or alcohol by the main characters, though the setting involves adult soldiers and a doctor mentioned in passing. Barney, the man who cares for the children, uses medical supplies like aspirin, but these are for legitimate health needs. While adult soldiers are present, they are not depicted in scenes of drinking or intoxication. The focus remains on the scarcity of resources, such as food and water, rather than recreational substances. Felix's perspective is focused on basic survival…

Heavy themes of loss, religious persecution, the Holocaust, and the death of innocence. Felix gradually realizes that his parents were not simply 'away' but were victims of the Nazi regime's systemic genocide.
