The Sun Witch (Fyne Witches, Book 1)

For 300 years, the Fyne women have called the mountain Orianan their home, inheriting the supernatural arts from their mothers--but a long-ago curse makes true love unattainable for them. When she meets the green-eyed soldier of her dreams, youngest sister Sophie discovers that she has been gifted with abundant fertility. Now, she and her lover must call on all their strengths, both earthly and supernatural, to fight the curse which promises to end their happiness.
