This book is well-written and exciting, with just the right amount of nods to historical accuracy to make it believable. Sort of. I was hoping for something a bit more realistic, minus the supernatural abilities and dystopian setting that seems to be the norm in recent young adult fiction. I gave it three (maybe even 3.5!) stars because I know that it will be enjoyed by many, and it is a finely crafted story...I just personally prefer something a bit more grounded in reality when it comes to dealing with the aftermath of an actual historical event (and given my penchant for all things WWII). And - spoilers - it also bothers me when there is no real ending to a book, leaving it open for a sequel.
