Sin, Substance and Solitude is the last book of the "S" series. In this book Ja'Nyia discovers the meaning of failure, lust, contradictions, toxicity, and vulnerability. Today she encourages you to change the root of your problems, and execute the next step to being who you need to be. Never let an item, person, or thing discuss who you are and your own identity. You are the key to success, failure, and healing. Remember, it's all on you.
