I have read it once. There is a crease mark on the bottom corner of the back cover (photo attached). This is a book that has been in someone else's possession, so you may feel the signs of use and wear that come with a used book. We kindly ask that those who are concerned refrain from purchasing. Please feel free to comment if you would like me to send photos of any areas of concern. We will use recycled packaging. We do not smoke and do not have pets.
