Every child of Eden fears the Red Death. All those afflicted with the plague die young, their souls stripped away as punishment for ancient sins long forgotten. For centuries, Guardians have protected Eden from the Red Death by killing outsiders who stray too close. They must keep Eden a secret if they are to survive. Seventeen-year-old Aaliss is a highly-trained and dedicated Guardian, but when her rather odd thirteen-year-old brother discovers a cure to the plague, her world is turned upside down. The discovery is a miracle, yet miracles are dangerous in Eden. The corrupt, all-powerful High Priest brands Aaliss and her brother Wilky as traitors, forcing them to run. They seek refuge in the last place Aaliss thought she’d ever go—beyond the boundaries of Eden, and into the land of the Soulless. Here they must navigate a medieval world filled with witches, magic, and warrior kingdoms run by Elders who are only a few years older than her. Aaliss yearns to return home to Eden, but she must protect Wilky at all costs. And when her heart tugs her deeper into the world of the Soulless, she questions everything she once believed, everything the Priests had taught her about those who live outside Eden—they are forever cursed, savage, soulless. Has her soul been taken? Will she and Wilky fall victim to the Red Death, or might they die sooner in the center of a battle that threatens to tear apart the Soulless world? Or... might Aaliss finally find, against all odds, what her heart has yearned for all along?
