Impossible
I read this when it first came out and really enjoyed it, so thought I'd re-read in preparation for the sequel that just came out.
Hrm. Sadly, it's much less good than I remember it being. Still an awesome concept, but the execution is poor. There's so little about breaking the actual curse, and so much about I don't even know what. This book is over 300 pages long and I couldn't tell you why it takes up that much space.
It's still fun, just somewhat disappointing as I remember loving this five years ago.
