Following the death of Tsar Alexei I, his eldest son, Fyodor III, ascended the Russian throne. However, Fyodor's paralysis and weak immune system often confined him to his bed, where his sister, Sophia, would diligently care for him. After Fyodor's all-too-early death, Sophia would defy the Russian nobility in attempts to place her younger brother, Ivan, on his rightful throne. One rumor would spiral into a series of violent uprisings and riots, and, as the dust settled, Sophia would rise to incredible power . . . but at a heavy price. Would she be able to protect her younger brother, and his throne? Or would she die trying?
