This is a set of two books: "The One Habit to Build an Unbreakable Mind" and "The Power of Letting Go: Making Work and Relationships Thrive." The books are covered, so there is almost no dirt or folding. However, "The Power of Letting Go: Making Work and Relationships Thrive" has slightly dirty page edges. I believe it doesn't affect reading, but please make your judgment based on the photos as these are used items.
