The Everlasting Heart Series is still in progress: there are two books so far, continuing the stories of love and adventure among the family of the Earl of Kendall and their Irish neighbors—sometimes friends, sometimes enemies. A third, The Constant Heart, will be forthcoming in 2018.
Diarmaid the Irishman is a special favorite of mine. It puts together two books in which Diarmaid, an Irish rebel, plays an important role. In The Divided Heart he introduces a young Anglo-Irish girl to the Irish side of her heritage; in The Defiant Heart he has chosen his own path as an Irish rebel, but has to come to terms with the consequences of that choice for himself and the girl he comes to care about.
