The Obsidian Tower The Ash Queen, Book 1, (Hardcover)

Princess Johanna is thrust onto the Throne of Solaria when her mother is killed protecting an ancient artifact within the Ivory Halls of the Obsidian Tower. Sitting on the Throne of Solaria is the last thing she expected to be doing, and the nightmares won't let her sleep. The only thing she needs is to finally ascend the Throne, and then she can finally start her hunt for revenge.

What she doesn't expect is being chosen by Arcanis, the Goddess of the Suns, and suddenly having the souls of four long-dead leaders occupying her mind. Or developing one of the rarest magic types in the world - the ability to manipulate time. Or having to travel across the world with her best friend and personal assistant to help the leader of another race find her kidnapped mate - who had been taken by the same people who killed her mother.

While balancing her quest for revenge against her mother's killer and the duty to protect her country and people, the new Queen comes to realize the relic stolen is far more dangerous and world-changing than she had been led to believe.
