The Mystic Archives of Dantalian

Lord Hugh Anthony Disward, known as Huey, inherited his grandfather's manor and its vast collection of rare books after his eccentric grandfather's passing. The will stipulated that he must take guardianship over the Bibliotheca Mystica de Dantalian, an archive containing forbidden knowledge, and care for Dalian, a mysterious girl who is, in fact, the archive itself. An old acquaintance of Huey's grandfather arranges a meeting, which inadvertently puts Huey and Dalian in danger when they discover the acquaintance is in possession of a cursed tome known as a Phantom Book.
