Ferris knows something is suspicious about Addie's arrival. She just can't figure out what. As soon as this estranged half-sister joins the picture, things turn strange: The sun never sets, then it never rises. Rain refuses to end, rivers glow, and fog swallows the town whole. Her parents are tense and secretive while Addie is an intriguing unknown. Ferris is pulled in two directions: The one that wants to unearth her family's secrets and the one that just wants to stay a kid with her best friend. On her own in a new town, Addie is supposed to shake off the demons that follow her through court orders, therapy, and ketamine treatments. Visions of her time months ago chase her and make it hard to concentrate. The already complicated life transition reaches a fever pitch when old romances turn up and her baby sister begins poking around the shadows of the reasons she came to town.
