I opened the book to a familiar scene. I knew these words by heart, but I read them anyway. Frodo had been stabbed by the Witch-king of Angmar. He was taken to the elves in Rivendell, where he was reunited with his uncle Bilbo. It was Bilbo who gifted his nephew with mithril armor and the magical sword named Sting.

I brushed my fingers over the yellowed pages, feeling the cold magical current beneath the words: Gutenberg’s lock, though I hadn’t recognized his magic at the time. I had been imagining the warmth of Rivendell, the sunlight and the gentle breezes, the sense of peace that filled the air, and then . . .

Like any child raised on tales of magical worlds beyond paintings and mirrors and wardrobes, I had yearned to enter Middle Earth, to reach through.

My entire hand had gone numb. For an instant, it was as if my fingers had transformed into living text, words in brown ink spiraling through my skin and muscle and bone.

I had screamed, flung the book across the room, and hadn’t touched another novel for almost a year. My parents, convinced I was on drugs, had forced me to see a therapist.

At the time, I hadn’t understood the words that tried to consume my hand. Nor had I seen them well enough to write them down. But by the time I entered college, I had taught myself enough to identify those partially-remembered fragments as Latin.

I could feel Gutenberg’s lock, like an invisible chapter squeezed into the book, deflecting and trapping any magic that leaked from the pages. In theory, it should do the same to anyone trying to reach in or manipulate the book, which meant a lock was impossible to reverse.

Of course, once you had yanked Conan the Barbarian’s sword out of a book to fight off a rabid weresquirrel, “impossible” lost a lot of its punch. If anyone could unlock a book, it was the man who had invented libriomancy. And the first step would be to acquire the original, locked texts.

I fanned the pages. The velvet-textured paper against my fingertips brought back memories of those early, untrained attempts at magic, many years after my late-night Tolkien trauma. As I began to figure out how to deliberately tap into that belief and love of the story, I had gone a little bit overboard. I almost flunked my senior year of high school, being too busy collecting things like a sonic screwdriver (which I had never figured out how to use), a crystal ball from L’Engle’s A Wrinkle in Time, an impressive array of swords, and the winged sandals of Hermes himself.
