I really like this story's plot line- makes me wish I'd written it. (But don't worry I'm not a thief

) It's really interesting, but I think you do need a better hook; the opening paragraph was a little low-key. (Maybe you could try pulling a Rick Riordan ((Author of the Percy Jackson books)) and have your first sentence key the readers into the action. Ex: "Even before he got electrocuted, Jason was having a rotten day." (From the Lost Hero.)
I also really like your characters. They're easy to identify with and fun to read about. I'd like to be more clued in on Maci's thoughts. One thing: I think Dustin and Maci's descriptions shouldn't be in the same paragraph, especially since there isn't much on Dustin and it goes into full detail about Maci.
Also, I noticed a few grammatical errors, mostly with commas. For example, "'Hey! What are we doing in Science Cammi?'" should have a comma after "Science." Microsoft Word or an editor would fix that for you if you plan on publishing it, but for now...
One last/more thing: With the scene about the cookie dough, it wasn't really confusing, per say, but I think Dustin overreacted- he had, like, an INSTANT freak-out. What was that about?
Maybe that's a lot, but I always have a lot of opinions

ANyways, the problems are all small things that would make your story a little better.
BTW I SO WANT TO READ MORE!
