The Sisters of Colford Hall Series by Deborah Macgillivray

Unlucky in love, the mistress of Filgannon must free herself from the curse of her island with the help of a clever green-eyed Irishman who has invaded her land and her heart. Original.

While his brother is in Scotland dethroning the Lady of Falgannon, Jago Mershan heads to Kentucky to do his share in avenging his father on the Montgomerie family. But his enemy's granddaughter Asha arouses powerful emotions in Jago, and not even her claims of paranormal happenings in her diner can quell his feelings for her.

Not even the ancient stone walls of her family's English estate can protect the third Montgomerie sister from her magical destiny - or from the wolfish charms of Trevelyn Mershan, who has come to share it."
