Ghosts Don't Get Goosebumps — Elvira Woodruff

During summer vacation in West Virginia, eleven-year-old Jenna quickly makes friends with Angel Always. When Angel learns that Jenna's five-year-old brother, Nelson, can't talk, she suggests taking him to the haunted marble factory late at night. That's where Angel and Jenna think they've seen a ghost with yellow wrinkly fingers and an arm "with lots of goose bumps all over it."

Angel is convinced Nelson will be shocked into speaking at the spooky factory. Jenna's scared but agrees when Zack, another visitor, says he'll join them. But no one could have predicted that the older kids would meet the ghost again before dark and that Nelson would mysteriously disappear.
