Professor Okonkwo-Vass arrives at Ottilie's shop with an unusual request: he wants her to bind his memories into a book before he loses them to something far less companionable than ordinary forgetting. As Ottilie learns the delicate art of memory-binding—capturing not just facts but the warmth and shape of remembering itself—the Professor reveals dangerous truths about the Archive, an ancient institution that collects not only forbidden knowledge, but the people who possess it.

With careful stitches and patient listening, Ottilie begins to understand why her Aunt Hazel kept so many secrets, and why some knowledge is worth protecting at any cost. But as the Professor's memories flow into handmade pages, both bookbinder and storyteller must face what it means to preserve a mind while losing the person who holds it.
