Rachel Carson’s eloquent book Silent Spring stands as one of the most important books of the twentieth century and inspired important and long-lasting changes in environmental science and government policy. Frederick Rowe Davis thoughtfully sets Carson’s study in the context of the twentieth century, reconsiders her achievement, and analyzes its legacy in light of toxic chemical use and regulation today. Davis examines the history of pesticide development alongside the evolution of the science of toxicology and tracks legislation governing exposure to chemicals across the twentieth century. He affirms the brilliance of Carson’s careful scientific interpretations drawing on data from university and government toxicologists. Although Silent Spring instigated legislation that successfully terminated DDT use, other warnings were ignored. Ironically, we replaced one poison with even more toxic ones. Davis concludes that we urgently need new thinking about how we evaluate and regulate pesticides in accounting for their ecological and human toll.

A Michael L. Printz Honor Book "This is East Texas, and there's lines. Lines you cross, lines you don't cross. That clear?" New London, Texas. 1937. Naomi Vargas and Wash Fuller know about the lines in East Texas as well as anyone. They know the signs that mark them. They know the people who enforce them. But sometimes the attraction between two people is so powerful it breaks through even the most entrenched color lines. And the consequences can be explosive. Ashley Hope Pérez takes the facts of the 1937 New London school explosion—the worst school disaster in American history—as a backdrop for a riveting novel about segregation, love, family, and the forces that destroy people. "[This] layered tale of color lines, love and struggle in an East Texas oil town is a pit-in-the-stomach family drama that goes down like it should, with pain and fascination, like a mix of sugary medicine and artisanal moonshine."—The New York Times Book Review "Pérez deftly weaves [an] unflinchingly intense narrative....A powerful, layered tale of forbidden love in times of unrelenting racism."―starred, Kirkus Reviews "This book presents a range of human nature, from kindness and love to acts of racial and sexual violence. The work resonates with fear, hope, love, and the importance of memory....Set against the backdrop of an actual historical event, Pérez...gives voice to many long-omitted facets of U.S. history."―starred, School Library Journal

The Sex Side of Life is a sex education pamphlet written by Mary Ware Dennett with a goal to educate her sons, because she was unable to find any adequate books on the subject. Many of the books on sex either contained inaccurate information or used fear and shame tactics to dissuade the youth from having sex. Therefore, she decided to write her own explanation using research and interviews with doctors. The pamphlet was twenty-four pages long. Dennett used scientific discussion of sex while also including the emotion side of sex relations. The pamphlet covered controversial topics including masturbation, sexually transmitted diseases, prostitution, and support for the use of birth control. Her views were considered radical for this time, because she was not promoting abstinence.

Charles Darwin published The Origin of Species, his revolutionary tract on evolution and the fundamental ideas involved, in 1859. Nearly 150 years later, the theory of evolution continues to create tension between the scientific and religious communities. Challenges about teaching the theory of evolution in schools occur annually all over the country. This same debate raged within Darwin himself, and played an important part in his marriage: his wife, Emma, was quite religious, and her faith gave Charles a lot to think about as he worked on a theory that continues to spark intense debates. Deborah Heiligman's new biography of Charles Darwin is a thought-provoking account of the man behind evolutionary theory: how his personal life affected his work and vice versa. The end result is an engaging exploration of history, science, and religion for young readers. Charles and Emma is a 2009 National Book Award Finalist for Young People's Literature.
