The Legend of the Last Library

"After a devastating Blight killed off all the trees, 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. That all changes when she decides to read the book. Beyond opening her imagination, the book contains clues that point to what could be the last library on Earth."--
