DON’T DIE [EPUB ebook] 

Fentanyl-laced cocaine almost kills Madison Avenue ad agency executive Katie Mc Farland. Her husband, Mac, an investigative reporter and author, is determined to disrupt the flow of deadly fentanyl, manufactured in China and smuggled into the United States by Mexican drug cartels. The drug contacts Mac developed are murdered, and he focuses on helping his wife face her addictions — a greater challenge than he ever imagined.
