"Publisher Eterna Cadencia wanted to find a way to create a sense of urgency when it comes to reading books. If you are like many people, there are books sitting on your bookshelf that you put there with the intention of reading, and you just haven’t gotten around to it yet. Sometimes books can sit on shelves for years before being read, and Eterna Cadencia wanted to find a way to motivate people to read them now.
What was the result? This is called The Book That Can’t Wait. It’s a book written with invisible ink, and there are about to be many more books published this same way too. It’s a special ink which responds to air and light, so the book is permanent until it’s opened, and then once the air and light hit it, it’s on a 2-month lifespan. That’s right, it will basically self-destruct in two months. The invisible ink will make all the text in the book disappear after that much time has passed."
