A tormented, passionate woman with one piercing grey eye, Kristopher Silverheart is a major thorn in the side of the Elect, Earth's increasingly oppressive religious rulers. Once one of their own, she is now an Outcast, one of the Fallen, someone who has strayed from the Just Path and must either repent or be destroyed. Unbowed and undaunted, Silverheart captains a band of Outlaws who make regular forays from their refuge on the planet Hafwei to liberate as many Outcasts as they can from persecution, imprisonment and death. Constantly by Silverheart's side is the beautiful and ethereal Heaven, her beloved companion, with whom she has a mysterious and unbreakable bond. When Heaven is kidnapped, Silverheart embarks on a reckless solo rescue mission into the heart of the enemy's stronghold to bring her back.
