An ancient book, a power untouched, and a heart unloved lead Keelin O'Brien from her graduate studies in Boston, to a small village on the coast of Southern Ireland. Determined to unearth the secrets lying hidden in the enchanted waters of the cove, Keelin has little time for a surly Irishman who infuriates her during the day and who haunts her fantasies at night. Inexplicably drawn to the woman who has stepped out from his dreams and into his world, Flynn fights a stubborn battle against his increasing attraction for Keelin. But forces unknown have better plans for the two.

The knight was supposed to be a man. Not me, Sophie MacKnight, a marketing associate from California. This must be a practical joke that the Scots play on visiting Americans. Because otherwise I’ve inherited a haunted castle in Scotland, along with one irritatingly sexy Scotsman, who would be delighted if I turned tail and ran. Frankly, I thought I would fly here, sell the heap of bricks, and head back home to a life that I…well, I was comfortable with at the very least. Instead, the people of Loren Brae are in trouble, and it appears that as the new owner of the castle.

Clare MacBride has her life in exactly the order she wants it. In a year, she’ll have finished her geology dissertation, though she’s no closer to figuring out the answer to one question that plagues her: Why does she feel stones pulse with energy? A centuries-old curse, a mysterious faction of protectors, and a mythological godstone all sound like Old World fairy tale nonsense to Clare. It only takes one rainy evening with a silver-eyed fae and a handsome stranger promising protection to rock her world forever.

In the unbearable heat of another sultry Washington, D.C., summer, a serial killer is on the loose. Dr. Tess Court, one of the capital’s most successful psychiatrists, wants nothing to do with the case—until the police convince her to lend a hand to the lead investigator, legendary ladies’ man Detective Ben Paris. Scarred by his family’s history, Ben has even less use for shrinks than Tess has for him—but the forces of animal magnetism and a shared desire to catch the demented criminal known as “The Priest” inexorably erode the walls they’ve built.

Imogen, captain of the Irish charter boat, Mystic Pirate, has little time for friends and doesn’t trust her lovers. Perhaps the real issue is that she can’t trust herself, as she hasn’t yet found a good explanation for why otherworldly images dance before her eyes. Half-convinced that she is one step away from losing her mind, just like her mother, Imogen prefers to spend her life at sea with the only family she knows—her crew members.
