Dorothea, the widowed Duchess of Berea, is still in mourning when two male visitors come calling — the first to her remote Irish estate since her husband died. One is her cousin, who draws her back into the dangerous world of demon hunting that is her family tradition.

The second, the mysterious Brown, promises to help her when her own family is unable to. Neither Dorothea nor Brown expects the sudden hot attraction they feel for one another. Dorothea, used to being the protector, discovers how dangerously appealing it is to have someone protect her. But is Brown someone she can trust when the demons start hunting the demon hunter?
