This book follows four ordinary children, Eric, Hans, Kate and Ruby (& one dog) as they grow up and find their lives intertwined in the years leading up to and during World War II. Eric and Hans come from Berlin, so the reader sees what life was like leading up to the war in Germany. Kate and Ruby are from Britain. All struggle through pretty normal bits of childhood set in a time of approaching conflict. I loved the book once it got going, though I found it a bit slow and confusing to keep track of the various characters at the beginning of the book. Once the book caught its stride and various characters met each other, it was not a problem, and the action pulled the reader along. Seeing family life from the two countries will help readers understand that war is made of regular people – not all evil or good Just ordinary folks caught in extraordinary times. The book has one of those satisfying endings that lets the reader know what happened to characters years after the main conflict is over. At least I always like to know that! The author also gives some background information at the end of the book of some historical facts about the world the children have inhabited. There is also a family tree at the end, indicating some of the characters may have been in another book by this author, The Skylark’s War.  (Perhaps keeping track of all Kate’s family members would have been easier if I’d read this earlier book.) Definitely one to include for students interested in historical fiction about WWII, especially because it includes a look at both sides of the war.
