In 2020, COVID-19 brought the globe to a standstill, elevating pandemics to the most important issue around the world. But is something worse ahead of us? Hosted by film and television star Lance Reddick, ‘Book of Secrets’ is a new series that asks the question: ‘What if there is a book that serves as a repository for America’s most closely guarded secrets?' The USA’s story can be told in many ways. While much of the history of the country is well documented and widely available, there is another deeper history, one that has been shrouded in secrecy and hidden from public view; these are the stories that Sky HISTORY will reveal.
