COVID 19 telah mengakibatkan seluruh ekosistem dunia lumpuh. Pandemik ini merupakan pengalaman pertama bagi mereka yang hidup di abad ke-21. Kemunculan virus ini telah menjadikan manusia seperti hilang punca dan membahagikan mereka kepada dua aliran pemikiran. Sesetengah pihak percaya COVID 19 ialah pandemik yang berlaku secara semula jadi yang berpunca daripada jangkitan haiwan kepada manusia. Di pihak yang lain pula, teori konspirasi yang mengaitkan COVID 19 sebagai senjata bio yang dicipta oleh China dan Amerika Syarikat mengambil tempatnya. Buku ini membahaskan kedua-dua pendapat bersandarkan dapatan sejarah dan sains. Coronavirus, adakah ia virus pandemik semula jadi atau senjata bio yang dibangunkan untuk menghancurkan dunia?
