"The anguish of an entire generation" is expressed by five Jewish teenagers whose diaries are excerpted and carefully documented here by Boas, who is a Holocaust survivor. David Rubinowicz (Poland), Yitzak Rudashevski (Lithuania), Moshe Flinker (Holland) Êva Heyman (Hungary) and Anne Frank (Holland) never met each other, nor did they meet Boas. Each teenager found a means of intellectual stimulation, and all remained ethically alive during a time when, for each, hate and bigotry seemed to prevail. They did not known their powerful written testimonies would inform and inspire survivors and later generations. McKissack's moving introduction suggests the chilling consequences of ignoring the types of "race superiority" alive today. (Age 12-adult)
