This collective biography/alphabet book defines a hero as “someone who tries to be their best self, who helps others, who makes the world a better place.” One Jewish hero is included for each letter of the alphabet. The 14 women and 12 men featured vary in terms of race and ability, as well as occupation. Notably, fully half are living.   “A, B, C—what type of hero will you be?” ask Cohen and Olitzky, encouraging readers to see themselves in the individuals profiled. Each entry includes a well-designed, stylized portrait in bright, balanced colors, showing the subject in action. The information provided is necessarily basic. The entry for J (“Jonas Jiggles a test tube”) includes an illustration of Jonas Salk standing before a set of beakers. The letter J is highlighted, and a caption in small print identifies him as the scientist responsible for the polio vaccine. Half the entries include an inspirational quote that doesn’t add much (for Olympic gold medal gymnast Kerri Strug, “Have a passion”; for Marvel publisher Stan Lee, “One person can make a difference”); backmatter with brief bios would have been more useful, given that not all the subjects are household names. The work concludes with the words “I will make a difference by…”—an opportunity for age-appropriate reflection.
