If you look at the book from the side, you’ll notice that it seems to have stripes. The darker pages tell a story from the earliest days of printing, when a mute boy called Endymion Spring was apprentice to Johannes Gutenberg, the inventor of the printing press.
The lighter pages tell the story of a book, also called Endymion Spring, bites Blake Winters, a teenager visiting England with his sister and mother. The book’s pages are blank, except for some thin lines, like veins, running all the way through. But when Blake opens it, some words appear, meant only for him.
