Continuing the struggle she began in Into the Dark Lands, Erin—newly dubbed Sara—is forcefully put to sleep for 300 years while her Lord finishes overtaking his enemies—and Sara"s kinsmen. After conquering and slaughtering the last of the Bright Heart lines, he awakens an amnesia-ridden Sara and assigns one of his slaves, a fellow "child of the blood," to comfort her. As Sara"s memory slowly returns and her rage intensifies, the Servants of the Dark Heart and the Dark Heart itself become increasingly dangerous to both her and her caretaker.
