Description[]
Have you heard about the Fear Street woods? Nothing lives in the Fear Street woods. No birds, no squirrels, nothing. Nothing -- but ghosts. No one ever goes into the woods at night. Not if they want to come out again.
But Dylan and Steve just found a cool tree house there -- one that's supposed to be haunted. Are the creepy stories true? Dylan and Steve are going to find out. They're spending the night in the tree house -- in the woods. Just the two of them.
And one ghost.
