The Prophecy (Reign Series #1)

Death has come to court. As the plague rages outside the palace walls, tormented screams and pleas for help go unanswered by the members of the French court sheltered within the castle. Mary Queen of Scots feels safe-but she doesn't know that someone using the secret tunnels may bring the threat inside.
Mary worries that those she loves--her husband Francis, and friends Lola, Bash, and Kenna--remain stranded beyond the gates, among the sick and dying. The infection doesn't distinguish between royals and commoners. Can they survive? And when Nostradamus receives a disturbing vision that portends Mary's own death, she wonders--how long will she reign?
