The Bloom of Regret. The Last Immortal, #48

For centuries, Rafael carried the burden of a choice he could never explain. Forced by an ancient vampire council to abandon the man he loved or watch him be destroyed, Rafael disappeared from Michel's life without a word. Michel spent hundreds of years believing the one person he trusted most had betrayed him. Now, when enchanted forests begin dying and magical gardens fall into corruption, Rafael is called back to the only place where his heart still belongs-the Last Bloom Garden.
The source of the spreading darkness lies within the roots of an ancient power, and the only person capable of helping him stop it is Michel. Their reunion is filled with anger, heartbreak, and memories of the love they lost. But as they journey through forgotten forests, enchanted orchards, and ancient sanctuaries, they uncover a terrifying truth: someone is harvesting regret itself, turning sorrow into a weapon powerful enough to destroy all hope.
The Thorn King, an immortal who feeds on grief, plans to corrupt every magical bloom until joy and forgiveness disappear forever. To defeat him, Rafael and Michel must confront the wounds they have carried for centuries and discover that some bonds cannot be destroyed by time, betrayal, or loss. Because love does not erase regret. It transforms it. In the final battle for the Last Bloom Garden, Rafael and Michel must choose between sacrifice and forgiveness, between the pain of their past and the possibility of a future together.
The Bloom of Regret is an emotional gay vampire fantasy romance about second chances, immortal love, healing old wounds, and the power of forgiveness to create something beautiful from the ashes of the past.
