In Atherton, the jingle of the ice cream truck isn't a treat. It's a trap.

For the children of Atherton, the distant, tinkling melody of the ice cream truck has always been a "spectral melody" used as a lure. But twelve-year-old Toby knows better than to run toward the sound. He sees the "Spectral Truck" for what it truly is, a ghostly vehicle that manifests physically but lacks a corporeal origin. When the truck's "Lullaby Phenomenon" begins to target his neighborhood, Toby must resist the "Psychic Onslaught" and uncover why children have been vanishing without a trace for decades.
