The Last Eclipse. Eclipsed by Desire, #10

The final Eclipse approaches-and Kael stands at its center. The cosmic entity Nysvarath calls him, a heart forged in fire and desire, demanding allegiance, control, and sacrifice. Kael's magic has grown beyond anything the triad has faced, molten lines of power surging through his veins, threatening to consume him. and everything he loves. Astrael, Riven, and Azariel must confront fears they never imagined: jealousy, loss, and the fragility of trust under impossible pressure.
Secrets are revealed. Choices are made. And in the Sunless Path, where shadow twists and light shatters, Kael's heart alone may hold the key to survival. But the cost is high. Azariel offers himself to the Eclipse to protect Kael. Riven and Astrael must choose between binding Kael or letting him shine unchecked. And the triad discovers that love-dangerous, passionate, and unbreakable-is a force that can fracture even the oldest, darkest cosmic powers.
In The Last Eclipse, the world is changed. Kael is changed. Their bond is stronger. and more dangerous than ever. The Eclipse whispers one final truth: "I will return for what began with your heart."Dark, intense, and unflinchingly emotional, this installment pushes the boundaries of love, magic, and desire in the Eclipse by Desire series.
