Elizabeth's half-brother, nine-year-old Edward, is king in name only. Thomas Seymour, brother to the ambitious duke who has seized power in this time of crisis, calculatingly works his way into Elizabeth's home in genteel Chelsea House. He marries Henry's widow, Catherine Parr, and uses his venerable charms and sexual magnetism to indulge his infatuation for young Elizabeth. Caught hopelessly under Thomas Seymour's spell, surrounded by kind friends and hidden enemies, Elizabeth can only follow her heart to ensure survival.
