Julie Sil­ver­stein is a coau­thor of Chutz­pah Girls: 100 Tales of Dar­ing Jew­ish Women (Koren). Julie wrote Chutz­pah Girls to hon­or the dar­ing Jew­ish men and women in her life, like her grand­moth­er, who, as a girl in Ger­many, brave­ly con­front­ed the Nazi police to demand the release of her father from unjust deten­tion. She hopes this book will be a key that unlocks the sto­ries of chutz­pah in your family.
