Honestly this ending was top-notch. Reminds me a bit of Tales from the Crypt honestly. I was not expecting it and I thought it was cleverly done. Sometimes i forget that R.L. Stine besides doing tons of teen horror, liked to play around with twist endings. Some of his Fear Street books did not end on a “happy” note. I liked the characters in this one and I was wrong about who the mysterious girl was and how she came about.
