There seems to be a mix-up in the title you're asking about. 'The Abducted Book' isn't a novel I'm familiar with, but your description made me immediately think of the book I did get abducted by last year: 'The Library at Mount Char'. It's not called that, but the plot is exactly what you're hinting at—a group of people 'abducted' by a mysterious, god-like figure to become librarians of esoteric, dangerous knowledge. The main plot kicks off when their 'Father' vanishes, and the adopted siblings, each a master of a strange catalog like death or languages, begin a vicious power struggle to control the library and, by extension, reality itself.
It's less about a physical book being stolen and more about the characters themselves being the abducted custodians of forbidden texts. The central tension comes from Carolyn, who seems the weakest, using her wits and knowledge of the library's brutal rules to outmaneuver her terrifying siblings. The mood shifts from bizarre dark comedy to genuine cosmic horror, especially when you realize what the 'library' truly is and what 'checking out a book' can mean.
