This meticulously illustrated picture book takes readers on a cross-continental tour in 24 hours, visiting 6 different deserts at different hours of the day. While exploring the desert, young readers can play hide and seek with all kinds of desert creatures! Every nook and cranny is filled with critters big and small for readers to identify using the matching key at the bottom of the page. However, these incredibly important, fragile ecosystems are in danger. On the daytime visits, children in grades 2-4 can learn about the challenges these deserts and animals face due to climate change, invasive species, and other threats. When returning to each desert at night, readers can also learn about what’s being done to protect these unique habitats. The deserts depicted are the Mojave, the Chihuahuan, the Great Basin, the Sonoran, Painted Valley, and Death Valley.
