THE 24th SHADOW

The 24th ShadowIn Glint Hollow, the past doesn't just haunt you. It leaves a trail.Twelve-year-old Vesper Lowen is a master of being invisible. In a town tucked away in a fog-choked valley, she is the "e;smudge on the glass,"e; the girl who survives by blending into the shadows of her middle school hallways. She doesn't expect to be noticed, and she certainly doesn't expect to be a hero.Then she meets Blue.A retired racing Greyhound with a scarred flank and soulful eyes, Blue is considered a "e;washout"e;—a dog too slow to ever win a trophy. But Vesper quickly realizes that Blue isn't staring at empty corners. He is tracking the Echoes: shimmering, violet-hued silhouettes of people exactly twenty-four hours after they've passed by.When Kaelen Voss, the town's golden boy, vanishes during the annual Harvest Festival, the police are left with a cold trail and a locked-down valley. Only Vesper and Blue can see the truth. They possess a decaying map of the crime, a flickering replay of the kidnapping that only they can follow.But the Echoes are governed by a brutal law of physics: The Rule of 86,400.Every second that ticks by in the present is a second of the past that vanishes forever. As the twenty-four-hour window begins to close, the violet trail starts to fray. To save Kaelen, Vesper must step out of the shadows and trust a dog that everyone else gave up on. Together, they must outrun the fading light—because when the clock strikes the twenty-fourth hour, the boy in the past will disappear forever.
