Query: suspenseful and scary

Had heard it was a great child's book, then I realized it was in fact more in the "Suspense/Thriller" genre...The scene where the mom cruises across town to stalk the son, raises a ladder to his window and sneaks into his bedroom is positively frightening - caught me offguard...well done! Not for the faint of heart...
