Aspiring historian Jayne Lyons has pinned her career hopes on proving that her ancestor, King Richard III, is innocent of the murder of the Princes in the Tower. While volunteering at the search for his missing grave, she is cast back into the brutal 15th century, in the middle of Richard’s army camp.

As Jayne realizes she may not be able to return home, she adjusts to her new life and finds herself falling for Richard, and becoming his mistress. She even starts entertaining the hope of saving him.

But the Princes are missing, and all evidence points to Richard. When he asks her to spy for him against his enemy, Henry Tudor, she must decide whether to help the man she loves, even though he may be one of history’s greatest villains.
