536 AD: The Worst Year to Be Alive

Constantinople. The year is 536. In the greatest city on Earth, half a million people look up at the sky — and something is wrong. The sun has gone dark — and it will stay dark for eighteen months. Crops fail from Ireland to China. Then, five years later, the deadliest pandemic the ancient world has ever seen arrives on the grain ships. This is the story of the year one Harvard historian called the beginning of the worst period in human history — and how scientists finally solved a 1,400-year-old mystery using tree rings, ice cores, and DNA pulled from ancient graves.
