Twenty-five years later, the reverberations of those unsolved cases continue to echo through the lives of those devastated by the crimes. Wyatt, the one teenage employee who inexplicably survived the movie-theater massacre, is now a private investigator in Las Vegas. A case unexpectedly brings him back to a hometown and a past he's tried to escape—and drags him deeper into the harrowing mystery of the movie-house robbery that left six of his friends dead.

Like Wyatt, Julianna struggles with the past—specifically the day her beautiful older sister, Genevieve, disappeared at the fair. When Julianna discovers that one of the original suspects has resurfaced, she'll stop at nothing to find answers.

As Wyatt's case becomes more complicated and dangerous, and Julianna seeks answers from a ghost, their obsessive quests not only stir memories of youth and first love, but also begin to illuminate dark secrets of the past. Even if they find the truth, will it help them understand what happened and why they were left behind that long and faraway gone summer? Will it set them free—or ultimately destroy them?
