How to Have a Thought: A Walk With Charles Darwin by Nicholas Day, illustrated by Hadley Hooper (Neal Porter Books, 32 pages, grades 2-5). Start with some rocks, a stick, and a loop to walk. That’s all Charles Darwin needed for his walks. He would walk the loop and pile up the rocks to keep track of how many times he had gone around. And the whole time he walked, he was thinking. Thinking about what he had seen during his years traveling around the world on the Beagle: the fossil of a giant sloth, a flightless bird called a rhea (which he actually ate by accident), and the finches with subtly different beaks. As he walked and thought, Darwin slowly developed his ideas about natural selection. There have been many great walkers–William Wordsworth, Albert Einstein, Virginia Woolf, to name a few–and you can be one of them too, with your stick, your rocks, and your ideas. Includes a four-page author’s note with additional information about Charles Darwin and walking, and a bibliography.
I’ve loved Nicholas Day’s longer works that combined science, art, and history using a tone that invites readers to share in his discoveries. He’s done it again, this time with a picture book that focuses on Charles Darwin’s walking, then weaves in all kinds of interesting information about his work on natural selection and evolution and ends by including readers with those who can walk and have great ideas.
How to Survive the End of the World: A Graphic Exploration of How to (Maybe) Avoid Extinction by Katy Doughty (MITeen Press, March 31, 2026, 256 pages, grades 9-12). How will humanity end? Pandemic, nuclear winter, climate change? Katy Doughty takes a look at the history and possibility of each catastrophe in a way that is serious, yet optimistic enough to conjure up the will to keep going. Each chapter includes an “Ask an Expert” section in which a scholar of that particular topic weighs in. The final chapter, “The End?” is a brief but inspiring meditation on the courage required to face the possibilities of humanity ending and to look for your own role in possibly changing some of those outcomes. Includes a list for further reading, source notes, and a bibliography.
When this book arrived in the mail for a preview, I felt some existential dread at opening the front cover, but I forced myself to read the first chapter (Plagues and Pandemics), and was pleasantly surprised by how interesting and thought-provoking it was, with the illustrations making it a pretty quick and engaging read. The end of humanity may lurk at the back (or front) of all our minds, and teenagers experiencing this angst for the first time will find some interesting and hopefully inspiring reading here.
