Healer Evi left two herbs for herself - yew (a quick poison that causes pain) and heliotrope (plunges you into a deep sleep). After the death of her lover, seventeen-year-old Evie Carew wants to get lost in the swamps. But when the seer Harker tells her that an important task awaits her, Evie's curiosity betrays her. What shell was he telling her about? And why can’t she get out of her head the thoughts of the Horseman Lorena, who saved her on the worst day of her life? And Evie learns that she is the Guardian of Death, the second of four Guardians with the power to return the amulets. These amulets - Life, Death, Light and Darkness - keep the balance of the world. To find the shell, Evie must trust the Healer's instincts and understand that love never dies.
