"The terrible beauty that is Ireland comes alive in this mighty epic that re-creates the Emerald Isle's fierce struggle for independence. Trinity is a saga of glories and defeats, triumphs and tragedies, lived by a young Catholic rebel and the beautiful and valiant Protestant girl who dified her heritage to join him."

I was 300 pages into it for the second time before I was sure that I had already read it.

Can't find, don't have any more.
