The majority of the book drags a bit. The ending really redeems the story and reminds me why this series is worth reading. I love Haddix's style of bringing these historical mysteries to life. Her storytelling skills and creativity never ceases to amaze me.

I feel like this book is my favorite so far in this series. As the book progresses, we develop a bond with Mileva and her remarkable perseverance and sheer brilliance. Haddix shows us the human side of Albert Einstein and the imperfections of our role models. I especially like the sophistication and honesty she carries when addressing the concepts of fate and free will. My only complaint is that the explanations for time travel are starting to have little foundation, constantly leading back to the idea that, “time is messed up right now, so we don't know why.” I feel like this is becoming a bit of an excuse to limit the options of our characters. However, I applaud Haddix for the effort in trying to keep her story on track while maintaining the laws of time travel she has created in this complex world of hers.

Another fantastic retelling of history by Haddix. The premise of the Romanovs is intriguing, but the story itself felt very slow until the end. I still feel like Haddix is making up the rules as she goes, using the excuse that time travelers were originally wrong and now anything can happen. But that doesn't stop me from wanting to read the rest of this creative series!

This series is one of my favorites. I feel that the explanation of tracers and the ripples in history are a bit fuzzy in this book. However, it's difficult to explain a concept as complex as time travel, and I think her ideas are very believable and creative.

A childhood favorite of mine. Haddix never fails to keep her readers on the edge of their seats.
