This reads as though someone took an old Fear Street novel (though not The Babysitter I, The Babysitter II, The Babysitter III, or The Babysitter IV) and updated it for adults. In other words, this has the same cheese vibe as R.L. Stine writing for YA, but with a more adult approach. Not as adult as old school Christopher Pike, but somewhere in there. This is straight up 90s kid horror at its best, even though this isn't horror, wasn't written in the 90s, and hits at about an 8th-9th grade reading level. It was just plain fun. I'm going to end up purchasing this one too.
*Please note, by calling it close to Fear Street, I'm not meaning to imply that there's any plagiarism - there isn't. It's just got the utterly ridiculous Fear Street vibe of 90s cheese, and that's the best way I can think to describe it.
*For those of you who are too young to have experienced the joy of Fear Street - these comparisons are good things, and it's not your fault you didn't grow up on cheese horror (or maybe it is, a bit). You still have time to go read some. Do it.
