Ah, damn. I already get the feeling that I won't enjoy reading this duology. There's nothing seriously wrong with the writing style or something like that, just ... the apparent themes, age group, tone and so forth don't click with me. Why force yourself when you *know* that your gut feeling is in 95% of the cases right? 
It's a pity due to the interesting concept (you start reading the book from one perspective and can always switch to the other perspective when you turn over the book and read from the former "back" of the book), but naaah, I'll pass.
