Ghost from Ghost Camp

This is the ghost girl from the book "Ghost Camp" by R. L. Stine

Goosebumps #45: Ghost Camp

In this story, Harry and his brother are going to summer camp.  But, when they get there, they notice the camp loves to play jokes on the new campers.  But the jokes are too scary.  First, a girl sticks her hand in the fire and does not have any burn marks.  Then, a boy sticks a fork into his neck, and jams a pole through his foot!  I did not like this story because it was too scary. The main character is Harry.
