A ghost story read aloud beats a ghost story on a screen for one reason: the scare arrives at the speed of your voice, and you're holding the dial. We've found October read-alouds are the year's most reliable — a kid who negotiates hard against twenty minutes of reading in July will ask for one more chapter of the headless horseman. Lamp low, blanket on, one chapter a night through the last week of the month.
The scare levels below run from genuinely tense (Sleepy Hollow, best from about grade 5) to eerie-but-gentle (Rip Van Winkle) to one-tale-a-night Grimm for the youngest. Every book's own page carries the details in its "Worth knowing" note.
