Quentin is the most annoying protagonist I have read in recent history if not my life. I started this book because my coworkers recommended it to me. I gave myself 50 pages to get hooked and found myself intrigued by the story on exactly page 50 despite finding it pretty derivative. Then 30 pages later I lost all interest. No real reason. Just decided I was sick of Quentin.
I read a summary of the plot, and I made the right choice to quit. I honestly cannot see how any part of what happens to Alice could be believable. It's definitely not "Harry Potter for grown ups" (newsflash: not just kids read Harry Potter).
