Sequel to the searing Once (2010), this tale of young people trying to survive in Poland during World War II is equally powerful. This title picks up where the first book ended, with narrator Felix and companion Zelda, 10 and six respectively, fleeing from a death-camp–bound boxcar. In the course of their flight there is always the danger of being turned in to the Nazis for a reward, as well as the imminent peril of being shot or starving to death. Taken in by a Polish woman, the children have a home, but danger is everywhere, especially for Felix, who is tormented by a sadistic boy determined to strip him to see if he is circumcised. If he uncovers a Jew, the boy will claim a reward, and Felix, Zelda and Genia, the farm wife, will be shot. Throughout, Felix takes comfort in the humorous tales of his favorite author, Richmal Crompton, a British writer. These references provide necessary light moments in a book that shows the passage of the children from innocence to terrible reality: There seem to be no happy endings for Felix. Despite all the grinding misery and the moments of sheer terror, Felix retains his humanity, and a reader surely must walk with the protagonists on their long and tortured journey. (Historical fiction. 10 & up)
