She was his to protect. She was his to love.

Heather Alwyn had never been to the Cornwall seacoast before and certainly never MacArran Grange, home of the handsome and brooding Ruarke, Duke of Arran. So why did everything seem familiar, even the Singing Caves on his property reputed to be haunted by the ghost of a young woman bearing the same name as Heather's mother? Heather is determined to discover their connection and find out why the ghost is calling out to her. But the duke is just as determined to keep her away from those caves. Why won't he help her? And why is she losing her heart to this daunting man who harbors secrets of his own?

Ruarke, Duke of Arran, knew there was something special about the beautiful Heather Alwyn the moment he set eyes on her. He is falling in love with her, but there are unnatural forces threatening to take Heather from him. How can he protect her from an evil he cannot see? Heather is drawn to the dangerous Singing Caves, and it will take all of Ruarke's love and strength to keep her from falling under the siren spell of the ghost who haunts them.
