This nonfiction picture book follows two scientists who spend the night collecting information about the flora and fauna of Florida's Everglades. Though the scientists are fictional, they are part of the real-life Florida Coastal Everglades Long Term Ecological Research project, a research team working to restore the Everglades to its natural state. As the duo works, background information is supplied as to why the existence of the Everglades is threatened. Also included are facts about some of the 68 endangered species and other unique creatures that inhabit the area, as well as details about the equipment used by the scientists to collect the data. Each double-page spread features a full-page painting opposite a page of text. The block of main text is balanced by a smaller block of caption-like text with definitions of some of the words used in the main text. This is an adequate supplemental introduction to the Everglades and the restoration project, though of limited research utility due to the format.-- "Booklist"
