Castle in the Rock — Eileen Jackson

Betrothed to one man, in love with his brother, she must choose...for her life hangs in the balance...

Fate has not been kind to young Rhonwen Morgan. a tragic boating accident on the Thames has snuffed out her mother's life. Now, alone in the world and virtually penniless, Rhonwen is drawn to her mother's homeland, Wales. She is in search of a family she is not even sure exists, with only "Glyn Dedwydd" and "Castell Craig"--strange words whispered in her mother's sleep--to guide her.

Once in Wales, Rhonwen finds contentment beyond the imagining of her strict London upbringing. And a surprising off of marriage comes from the dashing Cristin Caradog--heir to the Castell Craig estates. At first, Rhonwen is thrilled at the chance of becoming a part of such a grand old family. But Cristin's proposal seems strangely sudden. The question of her mother's past has taken some mysterious turns, too. And so do Rhonwen's feelings of Cristin's brother Bryn. Confused and frightened, Rhonwen is unaware that she, herself, is the key to her past. And her past could rob her of her future...
