Water Viper — R.J. Blain

During Starfall, magic flooded the Earth and destroyed most technology while humans developed strange new powers. As the scion of a male-dominated clan, Jesse should have risen to become a hero.

She chose to become a woman instead, ruining her hopes for the future.

Years later, weary of life as an assassin, she retires to enjoy raising horses and delivering messages. When her plans fall apart, she has one final chance to set everything right. Should she fail to redeem herself, she'll lose everything she's ever held dear, including her friends, her family, and her life.
