This book really, really wants me to like it—it keeps telling me, over and over and over, that only girls like me, girls who read all the right (fantasy) books and liked to make things up and were outsiders in groups, are interesting or cool or special. It's off-putting. I expect the authorial voice to offer me Turkish delight next. (Except she already put that in. Yes, the White Witch has read Narnia, apparently.)
All its influences are insufficiently digested into Story and the book comes out lumpy and awkward as a result. I'm very surprised it is not the author's first book.
