His Fierce Lycan Luna by Jessica Hall

Revelations have shattered everything they thought they knew. Ivy, a mere name, is not who she seems. She is Azalea, the long-lost princess of the Landeena kingdom. With this revelation, Azalea not only discovers her true identity but also the dormant Landeena power within her. This power, a force of nature, is the key to everything. Casting off the chains of her former oppression, Azalea emerges as a powerful force, ready to reclaim her birthright and seek justice for the wrongs she has endured.
King Kyson, torn between his obligations and his emotions for Azalea, finds himself at a crossroads. He must choose to support her rise to power or step aside. As Ivy dies and is reborn as Azalea Landeena, she is no longer the submissive figure of her past but a queen in her own right. She challenges everyone around her to stand with her or move out of her way.
Meanwhile, a sinister figure lurks within the castle walls, weaving a plot of revenge. Their actions threaten to either destroy the kingdom and Azalea’s rise to power. As secrets unravel and allegiances are tested, Azalea and Kyson must navigate political intrigue and betrayal.

Revenge is in the air, ready to topple one kingdom and wake another from the dead. In the middle of it all, a queen rises, fighting not just for revenge, but for her kingdom.
