I have to say, I wasn't exactly feeling super encouraged by the blurb. The mention of "jocks" and "cheerleaders" had me grimacing. It made the book sound like what far too many people expect YA to be: formulaic, fake and full of school-yard niches which don't often exist in the real world.
My worries about the book weren't exactly proven groundless. Many of the characters were typically two dimensional. "Cheerleader" Vicky was about as deep as a puddle. The "BFF" had so much impact on the story that I've completely forgotten her name. Cyrus, the "Hot New Guy" was too nice to evoke any realistic empathy. However, Mary wasn't half bad. She was a gothic-dressing, black-lipstick-wearing, clairaudient "freak". That in itself isn't exactly original, but there were aspects to her character which I got along with. My favourite thing about her was her ghostly pet dog called Chowder!
The story itself was by-the numbers, but not in a really bad way. It was nice to have some bubblegum for my eyes to chew on. There were some nice, unpredictable elements thrown in along the way, too. I liked that Mary could only hear ghosts, but not see them. I loved the idea of haunted items (especially the haunted desk in then guidance counsellor's office) and the ending wasn't what I'd dreaded.
Overall, if you're looking for a read that you can swallow whole in an hour after a busy, bookless couple of weeks, then Scary Mary might be for you. It's not great literature by any stretch of the imagination, but it's a nice little story with some nifty little quirks mixed in.
