Polly Michaels is trying to forget that her mom has cancer. She keeps busy at school and plods through a normal social life. Until a freak electrical storm and a unicorn appear in the orchard next to her house. Sy'kai wakes on an orchard floor to the smell of rotting cherries and wet earth. She doesn't know where she is-or what she is-but she knows something is hunting her. Polly recruits her friends to find the mysterious creature she saw from her window while Sy'kai, a confused shape-shifting endling from another dimension tries to piece her mind back together. Once the human girls find Sy'kai (whom they nickname Psyche) the mystery unravels and the danger facing all of them comes into focus. A gritty struggle ranges throughout the girls' rural hometown and in the wild terrain around it. All while two questions hang over their heads. Can an alien deliver a miracle for a human mother? Can a group of teens defeat an interdimensional demon?
