I really like the Boy in the Suitcase, so I was looking forward to this second book, but unfortunately this book is more like a cliche of the first book. the bad guys have no element to explain them, Nina has gone further away from believable.
plus- I have trouble with the notion of the book, that Nina is the good guy.
what's the point of trying to save the world if you sacrifice your own family?
I did like the "surprise" ending, although I saw it coming in some form.
