Son of the Morning

All of Linda Howard's novels are wonderful but this exceptional time-travel is her first foray into paranormal romance--and it's not to be missed.
Grace St. John, a scholar, unwittingly discovers the Knights of Templar's secret treasure. Suddenly, her life is upturned when she spies her boss murdering her husband and brother. With no reason to live, except to extract vengeance, Grace becomes a fugitive of the law as she attempts to find an explanation for this horrible act.
Grace simultaneously translates 14th century medieval documents written by Black Niall. This embittered knight reaches into Grace's subconscious and the two begin to share dreams 700 years apart. A scholar specializing in ancient manuscripts, Grace St. John never imagined that a cache of fragile, old documents she discovered was the missing link to a lost Celtic treasure. But as soon as she deciphers the intriguing 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 celebrated 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.
Summoning the magic of an arcane ritual, Grace steps back to the barren hills of 14th-century Scotland, enduring the perils of an untamed land to confront Black Niall, a fierce man of dark fury and raw, unbridled desire. Driven by a mix of fear and passion, Grace enlists this brazen knight to join her in a modern-day search for a killer.
In their quest to protect a timeless secret, they uncover a love for all time -- and a deadly duel of honor that risks everything they have.
