REVIEW: Janice L. Loper 5.0 out of 5 stars Emotional. Truthful. Intensely absorbing. Eloquent. November 29, 2018 Format: Kindle Edition You get such an emotional response from each page. Your mind shouts, “Yes, This is truth.” As you read. Some passages leave you bleeding and stunned. Others have you shaking your head. These collections and musings are quite stirring. The truth can be quite ugly.
