This book was fantastic. The characters were well-developed and overall consistent, and fascinating. They seem like full, real people. The story was an exciting ride and stays true to history. The characters felt appropriate to the time period, which made them more alive, and helped me care about them more than I otherwise would have.

I will say, I didn't buy that Ethan, as a total buffoon in all other respects, is some sort of incredible spy and can "talk himself out of anything" as he rarely does this. There were just a few times that his exploits strained credulity given how he was portrayed otherwise. Similar, some of the time jumping was a little confusing.

Overall, however, the good far far outweighed any little inconsistencies. This book is awesome, if you are looking for well-written, well-researched, fascinating, and fun historical fiction, this is the book for you.
