Story

In mid-September, the Hartson sisters rescue Joe and his ex-girlfriend Raina from a dark alley. Joe remembers being attacked by an elusive shadow and Raina urging him to flee. Their refuge at the Horiverti Residence is soon invaded by a mysterious woman in a black dress who fires bursts of energy. Another mysterious woman, Annie, intervenes and takes the group to the Enja Defense Science Institute to investigate.

Joe is initially uninterested, but a tracking device found on him makes clear that he cannot escape what is happening. In the Institute’s basement lab, the group uncovers a secret linking the shadowy attacker, a space blockade and a high-orbit space station. The investigation points to a wider web of religious wars, powerful words and an organization known only through Annie. As the pieces connect, they suggest a future that could transform the world, while energy and activity gather at the once-deserted Horiverti Residence.

Characters

The story follows a group whose members have their own thoughts and whose decisions shape how events develop. The initial characters include:

• Joe Castleton: Ophelia’s new tenant, who cannot remember anything from two years ago. He and Raina attended the same university and had a relationship, but they recently broke up, leaving him anxious.
• Raina Summers: A sophomore studying chemistry. Her nearly year-long relationship with Joe faded over the summer, and after they meet by chance on September 15, her life becomes increasingly unfortunate.
• Naomi Hartson: She lives with Ophelia, is around upper-elementary-school age, and does not attend school. She spends her days coming up with fun ideas, harasses Joe daily and consistently beats him at games.
• Ophelia Hartson: She lives in a suburban villa with Naomi, with no other family members. She works as a luxury-goods designer at a recently famous company and receives enviable treatment despite her young age.
• Annie Alois Schultz: Known for her intelligence and rare beauty, she has a powerful, mysterious presence that often leaves others at a loss. She enjoys this effect and appears during the battle against Chava, saving the group.
• Chava Fon: The stranger who breaks into Ophelia’s house, dressed and behaving oddly, with resentment in her eyes. She frequently checks a watch whose dial bears a Big Dipper pattern and mutters to it.
• Ember Chester: A gentle, smiling girl who often appears before Joe and seems close to him. She is unobtrusive, but sometimes appears in his bedroom in her underwear, suggesting a suspicious relationship.
