The Amnesiac Investigator and Her Shadow Are Saving Everything

She doesn't remember who she is. All she knows is that her name is Lavinia Vitelli, she is sixteen, and she is the youngest investigator in the Adventurers' Guild's Department of Unusual Affairs. Her file lists her survival rating as "Qualified" and her mental stability rating as "Qualified." Only the "Special Notes" section has been torn away, as if someone didn't want it to be read. She has a shadow. It moves and listens, and late at night it uses her fingers to draw deaths that have yet to happen. When danger approaches, it covers the back of her hand. When she is afraid, it presses close to her feet. It is the only thing in this world that will never leave her. But she is afraid of it, too. Everyone who has touched her shadow has died. The shadow remembers everything she has forgotten, but it says nothing. So she travels with this silent, dangerous, seemingly all-knowing shadow through one town after another, each tainted by anomalies. She saves many people. Each time, the shadow devours some of her memories as payment. When she wakes, a line of unfamiliar handwriting has appeared in her notebook: "You are saving everything. Please keep going."
