For fans of Tahereh Mafi's Shatter Me series and Joelle Charbonneau's Dividing Eden, Bridget E. Baker begins a saga of shocking truths, deadly intrigue, and sisterly betrayal among the descendants of Eve.

My mom should have killed me the day I was born.

Being a twin complicates the Evian line of succession, but Chancery Alamecha is fine letting Judica inherit the throne. After all, she's the stronger sister-the merciless fighter, the ruthless politician, and the groomed heir. But something unexpected happens when Chancery tries on her mother's staridium ring, forcing her into a role that she never wanted: the prophesied queen who will prevent the destruction of Earth.

Now I have to kill my sister.

Judica, enraged by this turn of events, vows to do anything to reclaim her rightful place as empress. Including challenging Chancery to a battle to the death. While Chancery is away training, she gets a taste of the human world, where she can do whatever she wants without genetic obligations. Now torn between a life she was born into and one that makes her happy, she must confront her treacherous sister-or cause the end of the world.
