Eilean was born a “wretched”—a lowly foundling raised by the Aldermaston of Tintern Abbey. Then she’s chosen to assist in establishing the new abbey of Muirwood, now the site of a castle in the swampy Bearden Muir. Eilean’s role is as night servant to the druid Mordaunt, the king’s exiled advisor—and prisoner. He’s clever, dangerous, and invaluable to the Aldermaston.
