I got this book for free when my library was giving away books. I have to say I have a hard time reading so I don't read much but this book was one of the best I've read. It's definitely made for a younger audience with how short the chapters and story itself is but it doesn't stop it from being a real nail biter. You really wanna know what happens next after each chapter and I gotta say the fact it was written in the 80s adds to the tension. One of my favorites and I will definitely check out more stuff from this author.
(My fave scene was the the restaurant with the mirror ceiling)
