Most difficult choice yet...

There were lots of great books in this version of MS and there were books that were left in the dust early, and rightfully so.  I found at times I was comparing apples to toenails because the voice was so different, written for completely different audiences.  I really liked all the books that made it to the end but I didn't have one standout that I was blown away by.  I have recommended all three to many others and some people LOVED Ivan  and other LOVED Counting by 7's.  I LOVED Bomb.  But I am a scientist and I liked the storyline.  I know you can teach Ivan at a variety of levels but it doesn't have the broader appeal that the other two have, I don't know anyone in my junior high who would just pick it up unless I told them to.  Counting by 7's was a harder sell to my boys but the girls loved it.  For me, Counting by 7's was lovely but in the back of my head I kept thinking that this would never, ever happen in the real world.  I just got stuck on it for better or worse.
I would have loved to pick Leonard Peacock but it didn't make it so, instead of picking what is good for girls or good for boys or what is most teachable, I am picking the book that I like best of the three: BOMB. Yup, one for the nerds!!
