R.L. Stine's The Haunting Hour
Don't Think About ItDVD - 2007
For goth girl, Cassie, fitting into a new school and neighborhood isn't easy, but she entertains herself by playing tricks on the "popular" kids and her little brother, Max. As Halloween approaches, Cassie's search for scares leads her to a mysterious Halloween store and an unusual book. When Max begs her to read the book to him, she gives in and disregards the warning about not reading the book aloud. But it's when they get to the last page of the book and its clear warning about the Evil Thing, that the spooky adventure really begins.
