One day, a Hungarian-French Jew and his father were rounded up by Nazis and brought to a prison camp. One day, they tried to escape, and failed. One day, they tried to escape, and succeeded. In a true story that resonates with his own family legacy, Michael Rosen, one of today's most esteemed poets and authors of books for children, draws on the real-life account of Eugène Handschuh, who escaped with his father from a convoy headed from Nazi-occupied Paris to Auschwitz. At once honest, approachable, and speaking to the resilience of hope, One Day features sensitive illustrations by award-winning artist Benjamin Phillips, as well as a note from the author providing historical context.
