How I Survived My Summer Vacation

When Stuart Glassman goes to a summer camp designed by genius director Gregory Stevens especially for kids who want to make movies, he has no idea what he's getting himself into. Sure, Stuart has the usual jitters about meeting new people and trying to fit in. But his biggest problem is that the camp really is haunted. And for some reason the ghost, a wise-guy named Robert Campbell, decides that Stuart is going to be his new friend. And then there's the matter of the sasquatch . . .

From the book

"Stand still!" said Robert. He put his hand on my chest. Then he put his hand through my chest. I felt as if every bit of warmth was being sucked out of me—as though I had been shoved out of the house on a winter day with no clothes on.
No hologram could do that.
"You really are a ghost!" I cried.
Robert rolled his eyes. "That's what I've been trying to tell you!"
I screamed and ran down the path.
