If you take a book with you on a journey, an odd thing happens: the book begins to read you.

A reflective remark about travel and reading, suggesting that being away from routine can make a reader notice their own reactions and assumptions more clearly through a book.

The idea is that a book can act like a mirror: in a new setting, what you focus on and how you respond reveals things about your mood, values, and inner life, so it feels as if the book is examining you.
