Blush sensuality level: This is a sensual romance (may have explicit love scenes, but not erotic in frequency or type).

Book four in the Panthera series.

The second oldest of an ancient race, Nicholas, Duke of Arrington, is austere, lofty and elusive. A widower with no wish to remarry, he never expects to meet Miss Regan Saunders during a walk through Parade Gardens. Aware she's his destined mate, he's fascinated. She's an Abcynian Guard. To many of his kind, it would be a relief to find a woman willing to guard his secrets. Due to horrific betrayal by his first duchess, and Regan's scandalous plan of being a doctor someday, he's hesitant to simply claim her, and instead court her in secret.

When Guards become the targets of a macabre killer, Nicholas stop at nothing to protect Regan, including marriage. Despite the circumstances, it isn't long before they profess their love and consummate their vows.

Their love will stand against many tests. As an enemy far closer than they realize threatens, their faith in each other will be strained.
