The dead won't leave her alone. For Cavilla, it's one case after another... Cavilla Ramirez is an average Peruvian teen, tethered to the 1990s rhythm of clarinet rehearsals, dog-eared Agatha Christie novels, and low-stakes schoolyard mysteries. But when a hit-and-run claims her two best friends, her world implodes-and then restructures itself in a seemingly impossible and unnerving way. Her friends aren't gone. Their ghosts linger, needing her help in solving their murder so that they can cross over. And it's not just them. Ghosts are everywhere, and somehow, she's the only one who can see them. With a protector in the form of a god-turned-cat, Cavilla becomes a reluctant guide between Peru's realms of the living and the dead. Solving murders and helping the dead find closure becomes her new normal. But every answer she uncovers tugs loose something else: long-buried secrets about her own heritage, secrets her aunt Tia Luz would rather keep six feet under. And as Cavilla finds out, not all ghosts need guidance. One presence stands apart, watching her... waiting. And he isn't asking for help. He wants her - or something she has.
