Meh? Not really. I loved the historical fiction aspect especially in a middle grade story talking about the Cold War. The relationship with Gillian and Eric was very sweet. I hated Savannah and how she pretended to be "dumb." I guess the point was to show people how intelligent you really are and you don't pretend to be anyone else. Although, these days kids try to appear superior than others, so again not sure how that concept fits in. Overall, another adventurous historical fiction story. Is it kind of strange that I expected there to be fantasy element?
