A toxic river divides nineteen-year-old Violet Bates’s world by gender.
Women rule the East. Men rule the West.

Welcome to the lands of Matrus and Patrus…

Ever since the disappearance of her beloved younger brother, Violet’s life has been consumed by an anger she struggles to control. Already a prisoner to her own nation, now she has been sentenced to death for her crimes.

But one decision could save her life.

To enter the kingdom of Patrus, where men rule and women submit.

Everything about the patriarchy is dangerous for a rebellious girl like Violet. She cannot break the rules if she wishes to stay alive. But abiding by rules has never been her strong suit, and when she is thrust into more danger than she could have ever predicted, Violet is forced to sacrifice many things in the forbidden kingdom … including forbidden love.

In a world divided by gender, only the strongest survive…
