"Damnation seize my soul if I give your quarters, or take any from you."
Orphaned at birth, Annalise and Alecai lives are eternally entwined in a horrible incident. Born on the same chilling night and endowed with powers beyond their control, their souls split in two. Each living with only half a soul, they are destined to die instantly. That is, until the wager is set. Their lives are spared, on one condition. On the eve of their sixteenth year, their training ends, and the ultimate war between good and evil begins. If one of them can claim the other half of their soul, they will become immortal; akin to a god amongst men. If neither can fulfil the task before their 21st birthday, they both will die.
Fitted with the powers of darkness, obedient Annalise is tired of being refined to the walls of Havenstone, the manor in which she is never allowed to leave. Ridiculed by her superiors and beaten when she does wrong, she wants nothing more than to be free of her life. She is tired of being treated like an outsider and a freak because of her supernatural abilities by all, aside from her mentor, Pryxah, a fallen angel sent by Lucifer himself to watch over her. Pryxah is cruel and seemingly never pleased with anything Annalise does, but is determined to mold her into a fine killer, and harness her abilities and wield them like a weapon. Annalise is desperate to escape, and if that means killing her counterpart for her soul, she will do it.
Alecai is opinionated and headstrong, gifted with the powers of light, and is eager to set out and be released from Alderthorne, the massive estate that separates him from the rest of the world. Taught by Calixto, an angel chosen to help him progress in his training, he becomes more and more skilled in the art of death. He wants nothing more than the simple wish to be whole, and will do anything it takes to obtain the other half of his soul.
The battle for beautiful redemption or eternal damnation begins.
