The subtitle—``A journey to the heart of a black hole—and into one of the greatest mysteries of the universe''—pulls readers into an exciting book on astrophysics, replete with spectacular full-color diagrams and sweeping illustrations. Among the numerous topics: the life cycles of stars; the formation and structure of black holes; detecting black holes from the outside and imagining them from the inside; Newton's and Einstein's theories of gravity; Hawking's theories about exploding black holes; the idea that the universe itself is a black hole. No introduction to black holes would be complete without some science-fiction scenarios, and this book has its share of them: What if an astronaut falls into a black hole? Is there another universe on the other side? Is time travel possible? Accompanied by sharp illustrations that are at once technical and entertaining, the information is presented in fragments- -isolated paragraphs explicate the different parts of the diagrams- -that encourage readers to choose their own paths. With rigorous writing and a good sense of humor, this book will be enjoyed by a wide range of readers. (glossary, index) (Nonfiction. 8+)

Brief yet inspirational, this story will galvanize youth to use their voices for change.
Testa’s connection to and respect for nature compelled her to begin championing animal causes at the age of 10, and this desire to have an impact later propelled her to dedicate her life to fighting plastic pollution. Starting with the history of plastic and how it’s produced, Testa acknowledges the benefits of plastics for humanity but also the many ways it harms our planet. Instead of relying on recycling—which is both insufficient and ineffective—she urges readers to follow two additional R’s: “refuse” and “raise awareness.” Readers are encouraged to do their part, starting with small things like refusing to use plastic straws and water bottles and eventually working up to using their voices to influence business and policy change. In the process, she highlights other youth advocates working toward the same cause. Short chapters include personal examples, such as observations of plastic pollution in Mauritius, her maternal grandparents’ birthplace. Testa makes her case not only against plastic pollution, but also for the work she’s done, resulting in something of a college-admissions–essay tone. Nevertheless, the first-person accounts paired with science will have an impact on readers. Unfortunately, no sources are cited and the lack of backmatter is a missed opportunity.

A wholly original novel that celebrates connection in unlikely places.
A 19th-century astronomy textbook connects two isolated teens in this epistolary collection of notes and drawings.
“Copernicus” is grieving their astrophysicist mother’s recent death. Their dad sent them to their grandparents in Green Bank, West Virginia, to complete senior year. A cryptic note their mother left behind leads the San Francisco native to an old textbook in the school library. Since the Green Bank Observatory’s sensitive equipment requires a ban on Wi-Fi in the area, instead of scrolling on their phone, Copernicus spends study hall creating fanciful artwork and writing letters to their mother in the pages of the textbook. After another student leaves a sticky note asking them to stop defacing the book, their exchanges evolve into true dialogue. “Kepler” is only in the school building early each morning, before she’s bussed to a gifted program. While she plans to leave the area for college, she’s proud of her Appalachian roots. The two, who appear white in the illustrations, ultimately join forces to investigate strange phenomena that occurred when Copernicus’ mother was in high school, referring to themselves and other members of their community through astronomy-related code names. Over the school year, they trade candid exchanges and challenge each other to grow. While their communications are confined to paper, their friendship feels organic and earned. Walker’s clever, eye-catching collages and drawings appear on the pages of a real historical astronomy textbook, incorporating the textbook’s contents in ways that maximize their effect.
