New York Times bestselling author Paula Brackston returns with a new, magic-infused series about Hecate Cavendish, an eccentric and feisty young woman who can see ghosts England, 1881. Hereford cathedral stands sentinel over the city, keeping its secrets, holding long forgotten souls in its stony embrace. Hecate Cavendish speeds through the cobbled streets on her bicycle, skirts hitched daringly high, heading for her new life as Assistant Librarian. But this is no ordinary collection of books. The cathedral houses an ancient chained library, wisdom guarded for centuries, mysteries and stories locked onto its worn, humble shelves. The most prized artifact, however, is the medieval world map which hangs next to Hecate's desk. Little does she know how much the curious people and mythical creatures depicted on it will come to mean to her. Nor does she suspect that there are lost souls waiting for her in the haunted cathedral. Some will become her dearest friends. Some will seek her help in finding peace. Others will put her in great peril, and, as she quickly learns, threaten the lives of everyone she loves.
