Back in the 90s, as a pre-teen and teen reading Point Horror and other YA horror, I was never a big fan of Caroline B. Cooney. Her stories were vague and not really creepy. I preferred the flesh-and-blood stalkers, the threatening notes and the creepy phone calls. As an older reader, I understand what Cooney is doing, but other than the terrific Freeze Tag, in which she nailed the concept, I'm still really not a fan of her work.
Yes, she has a whimsical, kooky writing style that is perhaps lost on younger readers, but does it make her work any better? As an adult reader, flowery and descriptive writing really doesn't get you far if you don't have interesting characters interacting in a cohesive plot. And Cooney just returns to the same well again and again and again, offering up the same-old same-old good Samaritan metaphor about characters choosing to do the right thing or not.
It's the same thing, every bloody book!
This time, four students sign up for a mysterious night class that doesn't even have a subject. They are asked by the mysterious ethereal Instructor to provide a Scare Choice, so that they can all scare a person. And thus we get the usual Cooney standby of making choices. Do they choose to participate or not? Do they choose to stand by and let something happen, or intervene and stop it? Do they choose to be good or bad? Basically, swap the vampire from her last trilogy with this book's Instructor, and you've got exactly the same damn book!
Even worse, this settles on being preachy, instead of letting the book's theme speak for itself. Instead, the characters are verbalising the moral of the story out loud, just in case you don't get it.
There's no reason to read this book, because it's a slower, more boring replica of all the Point Horror books she's written before. Stick with the wonderful Freeze Tag and skip this class, because the only thing you'll learn here is how to be bored.
