History of Love

I started reading The History of Love and it's compelling. In flipping through the pages (a bad habit, always jumping ahead and reading random later parts) I noticed that G-d's name, the name that traditional Jews don't write or pronounce or prounce the spelling of (Yud-Kay- Vav-Kay), is written many times throughout the book in actual Hebrew. This means the book has to be treated a certain way, due to the holy name written inside it.
