Across the Irish sea, her younger sister, Deborah Cavendish, is lonely and unloved. When her husband returns home to join the Ulster Volunteers and fight the government, she faces an agonizing choice - to end her affair with James Rankin, the trade union leader whom she she thinks can give her all the love her husband has denied her, or face social ostracism and the loss of her beloved son. When she reads about her sister's act of defiancé, she resolves to go to her aid.

Ireland in 1919 is seething with violence, tension and divided loyalties - and so is the heart of the beautiful, wilful heiress Catherine O'Connell-Gort. For Catherine, by heritage, is a glittering symbol of British rule and oppression - yet by inclination she is a traitor to her class. A fervent supporter of Sinn Fein, she is also the secret lover of Sean Brennan, an IRA volunteer who is being hunted by the police for terrorism and murder. When the British government decides to meet terror with terror, Catherine finds herself in a position of even greater conflict. Her father, a colonel in British Military Intelligence, recruits Major Andrew Butler, battle-scarred war hero and Irish landlord, to assassinate IRA leader Michael Collins. He also decides that the dashing major would make the perfect husband for his headstrong daughter ... In a violent climax of passion, guilt and betrayal, while her country hurtles towards civil war, Catherine faces and a agonising choice as she makes her final, fateful decision.

1685. King Charles II dies unexpectedly, and is succeeded by his brother James II, England's first Catholic monarch since Bloody Mary. English Protestants feel threatened, and King Charles’s illegitimate son, the handsome young duke of Monmouth, rises against his uncle in armed rebellion. The rebellion turns young Ann Carter’s world upside down. Eighteen years old, she is betrothed to Tom Goodchild, a Protestant shoemaker; but secretly loves Robert Pole, an officer in King James’s army, who offers to take her to London as his mistress. Ann knows it is her duty to marry Tom, but does not love him; so when he marches away with the rebels, she imagines him being killed – which would set her free. But she knows such thoughts are wicked; her father is a rebel soldier too, like all the men of her village. So who should she pray for, when musket balls start to fly? What matters most – love or loyalty? If God could see into my heart, she wonders, what would He tell me to do? Her father, Adam, is a brave man tormented by fear. He has two fears: first, that he may be a coward, and run from the enemy; and second, that he is not one of God’s Elect, and will go to Hell when he dies. But like all the men of Colyton, ‘England’s most rebellious town’, he marches to war, risking his life for what he believes. When England’s most notorious judge, Judge Jeffreys, is sent to punish the rebels, Ann and her father are faced with the hardest choices of all.
