Dark Witch by Nora Roberts
Iona Sheehan has always felt a powerful connection to Ireland. So when her beloved grandmother confesses an extraordinary family secret, she can't resist visiting County Mayo to discover the truth for herself. Arriving at the atmospheric Castle Ashford, Iona is excited to meet her enigmatic cousins, Connor and Branna O'Dwyer. And when she lands a job at the local riding school she is soon drawn to its owner - the charismatic, fiercely independent Boyle McGrath. Perhaps she has found her true home at last...
But Iona's arrival is no accident. The three cousins have each inherited a dangerous gift from an ancestor known as the Dark Witch. And they are about to discover that some old legends can return to haunt the present.
The first in a magical new trilogy, Dark Witch is a captivating story of love, family and destiny.
