As Henry VIII draws his last breath, two very different women, Jane Dudley, Viscountess Lisle, and Frances Grey, Marchioness of Dorset, face the prospect of a boy king, Edward VI.

For Jane Dudley, basking in the affection of her large family, the coming of a new king means another step upward for her ambitious, able husband, John. For Frances Grey, increasingly alienated from her husband and her brilliant but arrogant daughter Lady Jane, it means that she—and the Lady Jane—are one step closer to the throne of England.

Then the young king falls deathly ill. Determined to keep England under Protestant rule, he concocts an audacious scheme that subverts his own father’s will. Suddenly, Jane Dudley and Frances Grey are reluctantly bound together in a common cause—one that will test their loyalties, their strength, and their faith, and that will change their lives beyond measure.
