Cillian Pherson is the duke of Blackridge and chieftain to the legendary Pherson Clan, one of Scotland's oldest and fiercest. A strong leader with an honest warrior's loving heart, Cillian prefers settling clan wars and making sure Scotland maintains independence to sitting in the Grand Hall, listening to his father regale old stories. Cillian also has no thoughts of settling down to beget heirs, as his father constantly reminds him he must, until the night he gets a glimpse of his future.

Upon returning home after months away serving his king, Cillian brings back good news of a war, along with unpleasant news about his future. After an argument with his father, Cillian storms out of the castle and takes to the mountainous paths of his Scottish lands, only to witness a ship crashing against the rocks below the cliffs.

Now, Cillian must find a treasure that is missing from the wreckage—one the crew claims is the most-valued jewel aboard, and one he only caught a glimpse of.

Lady Aoife Bohannon knows there is more to this world than can be found within the walls of her castle, high atop the rocky cliffs on Beannacht Isle. Aoife loves nothing more than to ride through the fields toward the busy ports to watch her clan's merchant ships sail in and out. Aoife longs to go on a grand adventure, sailing the seas on her own ship, but at her mother's insistence, Aoife agrees to hold court to a would-be suitor and stay away from the ports!

But even with Aoife's best intentions to help her good friend, Aoife finds the call of adventure too hard to resist. She soon finds out that adventure is closer than she thinks, and right where she never would have thought she wanted to be.
