I received this book from the author who thought I might enjoy the time-travel aspects. And I did! The general storyline is a good one: there is a totalitarian country somewhere in Eastern Europe which is the only place where shape shifting is possible. And there is a tyrant that many in the population want to overthrow. We are following two older teenagers--one American who is from there but visiting and one who has grown up his whole life there--as they try to deal with the political situation and getting to know each other. The book was marred a bit by some lack of proofreading and also some lack of consistency. The main male teenager seems to both know and not know about American culture in ways that can be confusing. And there’s a lot of chivalrous behavior which doesn’t look terribly different from sexism and so it can be hard to know how to read. Ends on a cliffhanger, I will definitely read the next one.
