PreS-K--Splash down! In this narrative, a little silver submarine maneuvers past masses of busy waterfowl and sea life to plunge from lighted surface to deep darkness, calm to stormy conditions, and from one underwater environment to another. This large board book will delight the preschool and kindergarten crowd, especially those intrigued by nonfiction. They can follow the progress of the sub, identify the brightly colored ocean denizens, and wonder on the penultimate page, "Will the sub escape from the blue whale's underbelly?" Yes! The conversational text melds with the illustrations leading readers to want more. This is a 2017 French import and a 2019 English translation. VERDICT This title is extremely satisfying for the young reader that favors nonfiction. A board book must-have.--Nancy Call, formerly at Santa Cruz Public Libraries, Aptos, CACopyright 2019 School Library Journal, LLC Used with permission.
