Isaac Vainio is a Libriomancer, a member of the secret organization founded five centuries ago by Johannes Gutenberg. Libriomancers are gifted with the ability to magically reach into books and draw forth objects. When Isaac is attacked by vampires that leaked from the pages of books into our world, he barely manages to escape. To his horror he discovers that vampires have been attacking other magic-users as well, and Gutenberg has been kidnapped. With the help of a motorcycle-riding dryad who packs a pair of oak cudgels, Isaac finds himself hunting the unknown dark power that has been manipulating humans and vampires alike. And his search will uncover dangerous secrets about Libriomancy, Gutenberg, and the history of magic. . . .

Isaac Vainio’s life was almost perfect. He should have known it couldn’t last. Living and working as a part-time librarian in Michigan’s Upper Peninsula, Isaac had finally earned the magical research position he dreamed of with Die Zwelf Portenære, better known as the Porters. He was seeing a smart, fun, gorgeous dryad named Lena Greenwood. He had been cleared by Johannes Gutenberg to do libriomancy once again, to reach into books and create whatever he chose from their pages. Best of all, it had been more than two months since anything tried to kill him. And then Isaac, Lena, and Porter psychiatrist Nidhi Shah are called to the small mining town of Tamarack, Michigan, where a pair of septuagenarian werewolves have discovered the brutally murdered body of a wendigo. What begins as a simple monster-slaying leads to deeper mysteries and the discovery of an organization thought to have been wiped out more than five centuries ago by Gutenberg himself. Their magic rips through Isaac’s with ease, and their next target is Lena Greenwood. They know Lena’s history, her strengths and her weaknesses. Born decades ago from the pages of a pulp fantasy novel, she was created to be the ultimate fantasy woman, shaped by the needs and desires of her companions. Her powers are unique, and Gutenberg’s enemies mean to use her to destroy everything he and the Porters have built. But their plan could unleash a far darker power, an army of entropy and chaos, bent on devouring all it touches. The Upper Peninsula is about to become ground zero in a magical war like nothing the world has seen in more than five hundred years. But the more Isaac learns about Gutenberg and the Porters, the more he questions whether he’s fighting for the right cause. One way or another, Isaac must find a way to stop a power he doesn’t fully understand. And even if he succeeds, the outcome will forever change him, the Porters, and the whole world.

For five hundred years, the Porters have concealed the existence of magic from the world. Now, old enemies have revealed the Porters’ secrets, and an even greater threat lurks in the shadows. The would-be queen Meridiana, banished for a thousand years, has returned in the body of a girl named Jeneta Aboderin. She seeks an artifact created by Pope Sylvester II, a bronze prison that would grant her the power to command an army of the dead. Michigan librarian Isaac Vainio is powerless to stop her, having been stripped of his power and his place among the Porters by Johannes Gutenberg himself. But Isaac is determined to regain his magic and to rescue his former student Jeneta. With no magic of his own, Isaac’s must delve into the darker side of black-market magic, where he will confront beings better left undisturbed, including the sorcerer Juan Ponce de Leon. With his loyal fire-spider Smudge, dryad warrior Lena Greenwood, and psychiatrist Nidhi Shah, Isaac races to unravel a mystery more than a thousand years old as competing magical powers battle to shape the future of the world. He will be hunted by enemies and former allies alike, and it will take all his knowledge and resourcefulness to survive as magical war threatens to spread across the globe. Isaac’s choices will determine the fate of his friends, the Porters, the students of Bi Sheng, and the world. Only one thing is certain: even if he finds a way to restore his magic, he can’t save them all…
