Kieran is a hundred-and-twenty-year-old immortal, originally hailing from the harsh, famine-stricken life of 1880s Ireland. He has surpassed death and thrived, gaining wealth, power and knowledge. Azrael is the angel of death, but his mission is far from ominous. He is the protector of the grief-stricken, and the champion of lost souls. The two are polar opposites in mission and nature, yet are inexplicably drawn to one another. The Supreme One sees all, and when he discovers the truth about the relationship he is enraged. Their commitment to be together must be stronger than his determination to keep them apart.
