She Is the Dragon's Queen
Serena has always been haunted by strange dreams she cannot explain—an ancient palace, a mysterious black dragon, and a woman who looks exactly like her.
She believes they are nothing more than nightmares until she discovers that they are memories from a life she lived centuries ago.
Long ago, Serena was the Dragon Queen, the ruler who united humans and dragons. But her reign ended in betrayal when the people she trusted turned against her and left her for dead. Her memories were erased, her kingdom fell, and the dragons were forced into hiding.
Now, Serena has returned.
With the help of Kaelith, a powerful black dragon who has waited centuries for his queen, Serena begins to uncover the truth about her past. But the kingdom that betrayed her still hides dark secrets, and the mysterious Dark Crown threatens to awaken an ancient evil.
As Serena struggles between the person she once was and the person she wants to become, she must decide what kind of queen she will be.
Because this time, she isn't returning for revenge.
She's returning to protect the dragons, uncover the truth, and break the cycle that destroyed her first life.
She was betrayed once.
She was forgotten for centuries.
But the Dragon Queen has returned.
