The dark descent of Elizabeth Frankenstein
(Book)

Elizabeth Lavenza has been starved and beaten by her "caregiver" until she is brought to the home of Victor Frankenstein, an unsmiling, solitary boy who has everything-- except a friend. To escape from misery, Elizabeth does everything she can to make herself indispensable. She is taken in by the Frankenstein family and soon she and Victor are inseparable. But as the years pass, Elizabeth's survival depends on managing Victor's dangerous temper and entertaining his every whim, no matter how depraved. She is determined to stay alive no matter the cost... as the world she knows is consumed by darkness. -- adapted from jacket
