Bookish high school student Rintaro Natsuki is about to close the secondhand bookstore he inherited from his beloved bookworm grandfather. Then, a talking cat appears with an unusual request. The feline asks for—or rather, demands—the teenager’s help in saving books with him. The world is full of lonely books left unread and unloved, and the cat and Rintaro must liberate them from their neglectful owners. 

Their mission sends this odd couple on an amazing fantasy adventure, where they enter different mazes to set books free. Through their travels, the cat and Rintaro meet a man who leaves his books to perish on a bookshelf, an unwitting book torturer who cuts the pages of books into snippets to help people speed read, and a publishing drone who only wants to create bestsellers. Their adventures culminate in one final, unforgettable challenge—the last maze that awaits leads Rintaro down a realm only the bravest dare enter . . . 

An enthralling tale of books, first love, and coming of age, The Cat Who Saved Books is a story for those for whom books are so much more than words on paper.
