Guardian Angel. Arcana Europa

When nineteen-year-old Dominic Coville's parents die in an accident, leaving him not only alone but on the brink of poverty, he desperately searches for work and is thrilled when the post of secretary is awarded to him despite his obvious inexperience and ignorance. Mr. Wynyard Knight of Mandrake Abbey, however, gladly welcomes Dominic and earns the young man's immediate sympathy for his fragile health as well as gratitude for the promising new life now awaiting Dominic.
Inside rock and timber, hungry shadows seek... But unusual things soon happen and appear to focus solely on him, and Dominic begins to wonder about the true history of Mr. Knight, the strange young man haunting the third floor, and Mandrake Abbey. With the persistent and increasingly violent attempts at communication by an angry ghost shadowing his hours, Dominic struggles to unravel the mysteries of his new home.
And even with the help of a handsome young gentleman who's an aspiring supernaturalist as well as his clairvoyant sister, danger closes in far too quickly. Then it's only a matter of time before carefully constructed façades fall away, and the sickly, decaying underbelly of Mandrake Abbey's centuries-old collection of stone and timber will reveal itself. Set in an alternate England sometime before the mid-19th century, Guardian Angel weaves a tangled and dark tapestry of old magic, romance, and madness, a celebration of classic gothic fiction and its macabre sensibilities.
