I think this was a solid attempt. The story concept was interesting and the writing wasn't too bad. I really only had a problem with a few things, other than FFF. 
 First, I think Paige tried too hard making Amy seem edgy. I'm also not sure the name Amy Gumm really suits her either. 
 Second, readers are SMART PEOPLE. I promise you. Readers really are smarter than you think. Paige must have a low thought of her readers because of this line in particular: "Maybe it was stupid Stockholm syndrome, that thing people get when they start liking their captors." I don't even know where to begin with this line. That THING? STUPID Stockholm? And then the DEFINITION. Okay, now, correct me if I'm wrong, but most people have access to some sort of device that can tell them what Stockholm syndrome is if they can't understand by context clues. CLUES. NOT DEFINITIONS. 
 Then there's this gem of a line on page 251, "That was yesterday. Now it was today." REALLY? NO WAY. I could have NEVER put that together on my own. Luckily, those where the only two real atrocities that I picked up. Unfortunately, her editor should have before I did. 
 To me, naming a character is extremely important. There aren't many character names that I feel really don't fit. In this book, I didn't think Amy Gumm was fitting (I get the reference but come on). Nor was Ozma and Pete. Ozma is little too dumb of a name for a princess of Oz whereas, Pete is too normal for Oz. 
 Overall, I thought this book was an enjoyable read. It was a fun and interesting concept and the story definitely has potential. I'm curious to see where it goes.
