Wolf Storm

This book is about three kids and one old man; Cecil, Jeremy, ________, and _________. They are all actors in a new science fiction movie, which is filming on a isolated snowy mountain. The props they're using are amazing - tame wolves, monster suits, mechanical ice spiders, and other frighting but fascinating wonders of machine. It sounds like the dream job, being characters in a new movie, with real live wolves and all... but something doesn't feel right... it's like someone other than the brilliant director is watching them... and why are the wolves so edgy?
I give this book
