Showing The Lost Souls of Angelkov by Linda Holeman

Russia, 1861
Antonina's world is shattered one cold spring afternoon, when her only son, Misha, is kidnapped while out riding with his father, the Count of the Angelkov estate. With her husband injured, she turns for help to those closest to her: Grisha, the estate steward, a man whose stoic exterior hides a secret shame he has borne all the way from Siberia, his birth place; and Lilya, the maid who jealously guides her mistress's secrets - and affections.
At once sweeping and deeply personal, set against the period of upheaval and social revolution of Russia in the 1860's known as The Unrest, The Lost Souls of Angelkov is historical fiction at its finest.
