I appreciate the offer but I'm not in a position to purchase books right now. When I left my home I was only able to grab my stones, not the books. I'm hoping one of these may help me through a situation in which I'll have to be calm and logical during a potentially heated discussion. Do you recognize any here that may help? If not, no worries. I know the information is out there for me to find. I bought them from a guy with a youtube channel. You may have even shared his name here guiding me to him.
