When the World Was Ours by Liz Kessler

Three young friends - Leo, Elsa and Max - spend a perfect day together, unaware that around them Europe is descending into a growing darkness, and that events soon mean that they will be cruelly ripped apart from each other. With their lives taking them across Europe - to Germany, England, Prague and Poland - will they ever find their way back to each other? Will they want to? 

Inspired by a true story, WHEN THE WORLD WAS OURS is an extraordinary novel that is as powerful as it is heartbreaking, and shows how the bonds of love, family and friendship allow glimmers of hope to flourish, even in the most hopeless of times.
