After a treacherous journey and a life-shattering introduction to a twin neither knew she had, sisters Haidee and Odessa expected to emerge from the Great Abyss to a world set right. But though the planet is turning once again, the creatures of the abyss refuse to rest without another goddess's sacrifice. To break the cycle, Haidee and Odessa need answers that lie beyond the seven gates of the underworld, within the Cruel Kingdom itself. And though the shadows of the underworld hunger to tear them apart, these two sisters are determined to heal their world - together.
