After Sir Julian Carbourne is slain fighting for Charles I at Edgehill, in 1642, his daughter Frances seeks sanctuary in West Wales.

The fortunes of war change abruptly however and she is soon engulfed. The surrounding countryside is occupied by the Royalist Earl of Carbery, whose overbearing incompetence awakens rival Parliamentary factions. Rowland Laugharne, an honourable professional soldier reared in the household of the Earl of Essex, returns to Pembrokeshire to become their leader.

General Gerard, handsome and unscrupulous, is sent by Prince Rupert to win back the area. Changing loyalties amongst the gentry and the dubious activities of Mayor Poster of Pembroke produce a second bitter struggle, finally crushed by the formidable might of Oliver Cromwell.

Ruined by war, Frances is eventually restored by Luther, and her remarkable friendship with Nathaniel Owen. Whilst helping the helpless, she at last gains strength - from the dignity and courage of ordinary people.
