Hidden on the High Wire — Kathy Kacer

Irene grew up traveling around Germany with her family's circus, surrounded by her loved ones and thrilling the crowds with her performance on the high wire...until one day, the audience boos. The Lorch family is Jewish, and the increasing power of Adolf Hitler's Nazis has put them all in grave danger.

When the circus is forced to shut down and Irene's father is taken away, Irene and her mother must go into hiding with another circus. Every day is a frightening new kind of balancing act, caught between the desire to perform and the need to hide -- even in plain sight.
