In a world where paper is scarce and books are priceless, Juni Knox undertakes a dangerous quest to find a legendary lost treasure—the last library. Juni lives in a world without books. The Blight killed off all the trees, and paper is worth more than just about anything. Juni’s parents died when she was young, so now it’s just her and Grandpa Edgar. When she’s not in school, Juni and her friends Doler and Quaze turn to plifting—scavenging for any paper they can find. If Juni can find enough paper, she can pay for the health care Grandpa needs. So when Juni discovers a book—the first one she’s ever seen— hidden in a box in her grandpa’s closet, she’s both surprised and elated thinking of the money she could get for it. Grandpa, however, insists that she read it first. Beyond opening her imagination, the book contains clues that point to what could be the last library on Earth. If reading one book could change her life, what would access to thousands—or millions—of books do? While plifting, Juni meets Kobyn, who’s part of a secret organization eager to find the library. And then Juni meets Ullred O’Donnell, head of R&D for Novexus, a megacorporation that replaced the government and now controls all information. With an army of robot dogs, he warns Juni to abandon her quest—or else. Juni, Doler, and Kobyn must find the library and share it with the world before Novexus claims it.
