Well, I really liked it... 
 The book was REALLY, REALLY amazing but for a few things (maybe because I had such high expectations so it was easy for it to be disappointing). But I don't know, some stuff was just weird... like the Innovation horses, and the re-creation or whatever of the virus with what technology? I mean they can't cross a ocean but can genetically modify animals? It was just weird... And I can't help but feel that there was something lacking, especially at the ending, It was just suddenly everything was perfect and she went away, just felt a little to hurried... 
 And the letters, in the beginning they were great and explained a lot but towards the middle it kinda felt a little forced, and not the stuff 11 year old kids would talk about. 
 (view spoiler)[(oh yeah, was it just me or they relationship was entirely platonic? did anyone notice that they did not kiss? not even once!) (hide spoiler)] 
 Crap, I really wanted to love this book :(
