Hmmm.
When I opened this book, it had me from the get-go. I loved the preface and I was expecting more of it through the rest of the story. Unfortunately, I didn't get it. Ex-Appeal lost its appeal to me about a third of the way in, and from there on, I simply found it ... negative. Once I reached the end I was still waiting for the story to begin. I didn't feel that anything actually happened, and it didn't get anywhere.
Yes, there were a few bits that saved it, giving me hope that it would perk up - the Walker kids, the animal antics - but they turned out to be just rays with no sunshine. I liked the whole 'save the world' angle, but being a vegan and having an animal rights and fair-trade outlook myself, I couldn't stop muttering "what on earth". I don't feel that the revelant information was very well researched and the characters were the farthest thing from what they were trying to be passed off as. It all just came accross as a gimmick to me, something to stick in there in an attempt to give the characters some depth.
