From the back cover:

From a time when Ireland strained against the reins of English rule, comes a saga lush with enchantment, It begins of an afternoon when the wind blows wet from Galway Bay and a magnificent gray stallion appears in the Irish town of Carraroe. With the horse comes magic, for in its noble shape stands Ruairi MacEibhir, who has come in a time of great peril to win the heart of the woman he loves.
