This is a well-researched history of Russia and Ukraine, as the author takes us back and forth in time to discover how Putin came to power, as well as the strength of Ukraine in seeking independence and fighting back. This is listed as a children's non-fiction history book but I think it will appeal more to YA readers as there is a lot of dense information, unfamiliar names, and the complicated history of Russia pre- and post- Soviet Union. That said, I think now more than ever readers have to understand Eastern European history to make intelligent connections to current US events. This is a very reader-friendly book for adults, and I recommend all adults who are concerned about Putin's threat to not only Ukraine but democracy around the world.
