The first novel in the Celtic-Arthurian Bride of Alba series, Healer centers on Brenna of Gowrys. After ensuring the safety of her infant daughter with a trusted nurse, Brenna’s mother killed herself to escape the clutches of the neighboring O’Byrne clan leader, who murdered her husband moments before. The dying woman prophesied about her daughter, forcing Brenna to live as a fugitive in the wilds with only Faol, her wolf, as her companion. But the early guidance of her nurse and a mentoring monk has helped Brenna hone her God-given healing skills, and with the monk’s assistance, she secretly restores local people to health, even though her acts of mercy and kindness place her at great risk.
Together Brenna and Faol fend off an unknown assailant who attacks and severely injuries a stranger. Brenna drags the victim to her cave home, where she heals and restores him, unaware that he is Ronan, the O’Byrne prince—eldest son and heir of her father’s murderer—who doesn't reveal his identity until they fall in love (which Windsor honestly portrays without the extremes of explicit detail or unrealistic purity).
