I found this book tedious. Maybe it's because the American Revolution is not of great interest to me, but I also found there wasn't much of a plot and very little action, which made the books in this series entertaining if nothing else. Also, I think my opinion of this book was affected by the various annoyances and problems that have accumulated over the past 9 volumes. For one, despite this being a series predicated on time travel, the issue of time paradoxes is more or less ignored. Every time the topic comes up, it gives Elizabeth a "headache" at which point she just chooses not to worry her pretty little head about it. The mechanism of time travel is not explained and there is no attempt to do so even in the most basic sense. It just happens. There are several plot lines that run through the series that just end up abandoned with no explanation. Like what happened to that list from Simon's grandfather with people they had to save? That was just forgotten. The pretext for time travel became more and more convoluted and "thin." Finally, Simon and Elizabeth's relationship finally got too irritating. He is possessive and she is infantilized, which is only accentuated by constant statements along the lines of "... but it's not like he tells me what I can and can't do." This is a dynamic VERY reminiscent of Twilight. It would have been nice to see their relationship grow into an actual partnership. I think I am ready to be done with Simon and Elizabeth.
