An excellent introduction to a familiar scientific puzzle.



Scientists and citizen scientists investigate monarch butterflies.

The first question was where the butterflies went in the fall. After the discovery of their wintering colonies in the oyamel forests of Mexico, the question changed to why their numbers have dwindled. Scientists point to a number of possible causes: weather variations and climate change; habitat reduction; herbicide use that has reduced the population of milkweed, where monarchs lay eggs and their caterpillars feed, and other wildflowers, where adult butterflies feed during migration; widespread use of neonicotinoid pesticides; and the rise of a disease due to garden planting of a winter-blooming milkweed species that encourages the butterflies to overwinter in Southern states. Hirsch, a former biologist and graceful science writer, explains the monarch life cycle and its complex migration clearly, setting the stage for her exploration of the many mysteries that still surround the population’s ups and downs. She stresses the hopeful fact that monarchs can bounce back relatively quickly, because they lay so many eggs, and she offers realistic options for readers to participate in research and to encourage butterflies. Her clear explanation is attractively presented, illustrated with stock photographs of butterflies and some human researchers (of varying ages and ethnicities) as well as with occasional appropriate charts, all supported by extensive backmatter. Sadly, the index is skimpy, a disservice.

An excellent introduction to a familiar scientific puzzle. (author’s note, glossary, further reading, become a citizen scientist, plant a butterfly garden, source notes, selected bibliography, index) (Nonfiction. 9-14)

Contentwise, an arbitrary assortment…but sure to draw fans of comics, of science, or of both.


Flash, Batman, and other characters from the DC Comics universe tackle supervillains and STEM-related topics and sometimes, both.

Credited to 20 writers and illustrators in various combinations, the 10 episodes invite readers to tag along as Mera and Aquaman visit oceanic zones from epipelagic to hadalpelagic; Supergirl helps a young scholar pick a science-project topic by taking her on a tour of the solar system; and Swamp Thing lends Poison Ivy a hand to describe how DNA works (later joining Swamp Kid to scuttle a climate-altering scheme by Arcane). In other episodes, various costumed creations explain the ins and outs of diverse large- and small-scale phenomena, including electricity, atomic structure, forensic techniques, 3-D printing, and the lactate threshold. Presumably on the supposition that the characters will be more familiar to readers than the science, the minilectures tend to start from simple basics, but the figures are mostly both redrawn to look more childlike than in the comics and identified only in passing. Drawing styles and page designs differ from chapter to chapter but not enough to interrupt overall visual unity and flow—and the cast is sufficiently diverse to include roles for superheroes (and villains) of color like Cyborg, Kid Flash, and the Latina Green Lantern, Jessica Cruz. Appended lists of websites and science-based YouTube channels, plus instructions for homespun activities related to each episode, point inspired STEM-winders toward further discoveries.

Contentwise, an arbitrary assortment…but sure to draw fans of comics, of science, or of both. (Graphic nonfiction. 9-12)

A splendid volume for young adventurers.



Based on her work with middle-school students, Long offers lessons on how to stay healthy and out of trouble while awaiting rescue, the same lessons taught to adults in her survival classes.

Her matter-of-fact, no-nonsense tone will play well with young readers, and the clear writing style is appropriate to the content. The engaging guide covers everything from building shelters to avoiding pigs and javelinas. With subjects like kissing bugs, scorpions, snow blindness and “How going to the bathroom can attract bears and mountain lions,” the volume invites browsing as much as studying. The information offered is sometimes obvious: “If you find yourself facing an alligator, get away from it”; sometime humorous: Raccoons will “fight with your dog, steal all your food, then climb up a tree and call you bad names in raccoon language”; and sometimes not comforting: “When alligators attack on land, they usually make one grab at you; if they miss, you are usually safe.” But when survival is at stake, the more information the better, especially when leavened with some wit. An excellent bibliography will lead young readers to a host of fascinating websites, and 150 clipart-style line drawings complement the text.

A splendid volume for young adventurers. (index not seen) (Nonfiction. 9-14)
