I still love the concept behind this series, although I found this book to be less captivating than the first two.
This time, Haddix's time traveling series takes us to early America where Andrea learns that she is actually Virginia Dare. However, immediately upon arriving, the kids find themselves in lots of trouble. They've lost the Elucidator (which allows them to communicate with the time-travelling adults who are helping them) and it seems that someone out there is trying to sabotage their mission to fix time and bring Andrea back.
I found this book to be more confusing than the previous two. It seemed to get bogged down by too much time paradox talk, and incessant mention but brief explanation of "tracers". By biggest complaint though was the ending. Haddix is known for being fond of the cliff-hanger ending, but this one was such a sheer drop that it didn't seem like an ending at all. I think my book is missing a few chapters! Virtually nothing is resolved and the characters are about to start off on an off-shoot to their original mission when, all of a sudden, the book is over. That just seems like the author ran out of time and decided, 'oh well, I'll just finish this story in the next book!"
