Did you know there’s a secret daily flight from the United States to Cuba? Or, that in 1966, the U.S. government smashed a bacteria-laden light bulb inside the New York subway system? Or that there are quite a few abandoned underground New York subway stations? Or, that there’s an entire (now-abandoned) underground movie theater in France? Of course not, because they are secrets. And this book is full of them. That’s why it’s called [insert eerie music here] the Book of Secrets. OOOOoooooo.
