World in a Mirror

The story follows an interstellar expedition that meets a planet whose people superficially resemble humans but exhibit mirrored anatomical and social conventions — reversed finger order, left-handed greetings, and facial expressions with opposite meanings. Translation technology and synesthetic architecture reveal cultural differences, while earlier reckless action by a younger crew member that destroyed native hatchlings heightens mistrust. Debates over driving customs, food ethics, and diplomatic procedure force the explorers to confront how small misunderstandings and individual misconduct can have grave consequences for first contact and the moral duty of visitors.
