The riveting historical adventure that began with Grave Mercy (2012), tells the story of another 15th-century "handmaiden to Death," Lady Sybella. Raised in terror by her father, she arrives at the convent’s doorstep half mad. Those that serve Death are only too happy to offer Sybella refuge, but at a price. Naturally skilled in the arts of death and seduction, the convent views Sybella as one of their most dangerous weapons. Years later when she is forced to return home, Sybella wonders if she will find peace with the choices she's made and if she will ever have something other than vengeance to live for.
