Among the rising tide of series nonfiction about government and citizenship, these titles in the Our Values series take on core principles underlying a free, democratic society. After covering the concept of identity in broad terms, Identity and Gender offers a lucid, pointed explanation of the gender spectrum, gender identity, and the difference between sex and gender. A repeated exhortation to respect everyone's gender identity drives the points home. Each spread includes plenty of full-color, labeled photos supplementing the text, and the accessible language is very inviting. Though these volumes might raise more questions than answers, those questions will likely lead to meaningful, thought-provoking conversations.
