New York Times bestselling author Linda Howard captivates readers in the deeply romantic tale of a contemporary woman who unravels an extraordinary mystery from the past—by living it. A scholar specializing in ancient manuscripts, Grace St. John never imagined that a cache of old documents she discovered was the missing link to a lost Celtic treasure. But as soon as she deciphers the legend of the Knights of the Templar -- long fabled to hold the key to unlimited power -- Grace becomes the target of a ruthless killer bent on abusing the coveted force. Determined to stop him, Grace needs the help of a warrior bound by duty to uphold the Templar's secret for all eternity. But to find him -- and to save herself -- she must go back in time . . . to fourteenth-century Scotland . . . and to Black Niall, a fierce man of dark fury and raw, unbridled desire. . . .
